EditorialT02-4.2.4 Character repertoires

The wrong standard number 19075 appears in the lead text of the third paragraph.

SolutionModify the lead text of third paragraph as follows:

The following character repertoire names are specified as part of ISO/IEC 19075:

See comment.

T02-JPN-002 4-Minor Editorial

T02-4.4.3 Operations involving numbers

In the 5th list item in the first paragraph, Subclause 4.10.6,“Operations involving multisets” is referenced for <max cardinality expression>. However, the <max cardinality expression> is not mentioned in Subclause 4.10.6, because a max cardinality is a property of an array type, not of a multiset type.

SolutionModify the 5th list item in the first paragraph as follows:

— <max cardinality expression> (see Subclause 4.10.5, “Operations involving arrays”, and Subclause 4.10.6, “Operations involving multisets”) operates on an array argument and returns an integer.

See comment.


T02-4.15.2.3 Temporary tables

The term “temporary base table” appears in the first paragraph and does not appear anywhere else in the standard. The term “temporary table” is the correct term, because of the definition in the lead text of Subclause 4.15.2 that a regular base table is either a regular persistent base table or a temporary table. In addition, a period is missing in the first sentence in the first paragraph.

SolutionModify first paragraph as follows:

A temporary base table is either a global temporary table, a

T02-4.15.7 Table descriptors

The word “descriptor” is the correct word rather than “description” in the 3rd list item of the 3rd paragraph.

SolutionModify the third list item of the 3rd paragraph as follows:

The description descriptor of each period defined for the table.

See comment.


T02-4.15.10Operations involving tables

Although the 6th paragraph describes the primary effect of a delete statement on a regular base table and derived table, the term “base table” appears in the second sentence of the paragraph. It is incorrect, because a base table may be not only a regular base table, but also a system-versioned table.

SolutionModify 6th paragraph as follows:

The primary effect of a <delete statement: positioned> on a regular base table T or a derived table T is to delete exactly one specified row from T. The primary effect of a <delete statement: searched> on a regular base table T or a derived table T is to delete zero or more rows from T.

See comment.

T02-JPN-006 3-Major Editorial

T02-4.15.10Operations involving tables

The description of the primary effect of a searched delete statement on a system-versioned table should be separated from that of a positioned delete statement just like that of a regular base table in 6th paragraph of the same subclause, because the number of rows for deletion is different between those two types of delete statement.

SolutionNone provided with comment.


T02-4.19.9 Known functional dependencies in a <table factor>

The term “BUCset” without hyphen appears in the second sentence.Solution

Modify the text of Subclause:

Let R be the result of <table factor> TF. Let S be the result of <table primary> immediately contained in TF. The counterparts of the BPK-sets and BUC-sets of S are the BPK-

sets and BUC-sets, respectively, of R. If A ↦ B is a functional dependency in S, and AC and BC are the counterparts of A and B, respectively, then AC ↦ BC is a known functional dependency in R.


T02-4.23.3.2Unique constraints

The condition for satisfaction of the unique constraint without a <without overlap specification> is described in the third paragraph, which reads:

A unique constraint that does not include a <without overlap specification> on a table T is satisfied if and only if there do not exist two rows R1 and R2 of T such that R1 and R2 have the same non-null values in the unique columns.

This condition is incorrect in case of a system-versioned table, because uniqueness is required only for rows with system time as of current timestamp.



T02-4.23.3.3Referential constraints

The semantics of referential check described in the second and third paragraph are incorrect in case of a system-versioned table, because only rows with system time as of current timestamp are involved with referential check.



T02-4.24.8 Known functional dependencies in a <table primary>

Since the symbol TQN is defined immediately after the first appearing <table or query name>, TQN indicates just that <table or query name>, but cannot indicate the second one, which is contained in <only spec>, in the third list item in the second paragraph, which reads:

If TP immediately contains a <table or query name> TQN or an <only spec> that contains a <table or query name>, then the counterparts of the BPK-sets and BUC-sets of TQN are the BPK-sets and BUC-sets, respectively, of R. If A ↦ B is a known functional dependency in the result of TQN, and AC and BC are the counterparts of A and B, respectively, then AC ↦ BC is a known functional dependency in R.


T02-JPN-011 4-Minor T02-4.36.3 An intransitive verb “execute” appears without an object in 4th paragraph. In See comment.

Editorial Properties of SQL-transactions

other than Subclause 4.41.3, the similar occurrence of “execute” appears in several location in this standard.

SolutionModify 4th paragraph.as follows:

An SQL-transaction has a transaction timestamp, a value of an implementation-defined timestamp type that is used to set the values of system-time period start and system-time period end columns of rows, if any, modified by the execution of an SQL-data change statement in this SQL-transaction. The transaction timestamp is set by an SQL-implementation before any SQL-data change statement executesis executed in that transaction and, once set, remains unchanged during that SQL-transaction.


T02-4.36.7 Encompassing transactions

The term “isolation level” appears in the second list item of the 4th paragraph. The term “transaction isolation level” is correct.

SolutionModify the first sentence of the second list item of the 4th paragraph.as follows:

If the SQL-transaction has a transaction isolation level of READ UNCOMMITTED, then the branch of the SQL-transaction may have an a transaction isolation level of READ UNCOMMITTED, READ COMMITTED, REPEATABLE READ, or SERIALIZABLE.

See comment.


T02-4.38.4 SQL-session context management

The term “SQL-session execution context” appears at the end of the 4th paragraph. The correct term is “SQL-session context”, because this paragraph is involved with a stack of SQL-session contexts.


The <value specification>s CURRENT_USER and CURRENT_ROLE identify the user name and role name on top of the authorization stack in the top of the stack of SQL-session contexts. The <value specification> SESSION_USER is the value of the SQL-session user identifier in the latest SQL-session execution context.

T02-4.38.4 SQL-session context management

An incorrect term “user name” appears in several places. The correct term is “user identifier”.

SolutionReplace the term “user name” in the 3rd, 4th, 5th, and 8th paragraphs with “user identifier”.

Modify 3rd, 4th, 5th paragraph.as follows:

Each SQL-session context contains an “authorization stack”. Each cell of the authorization stack is a pair, a user identifier, and a role name. Whenever an SQL-session context is created, the base of its authorization stack is initialized with the SQL-session user identifier for the user name identifier and the null value for the role name.

T02-6.10<window function>

After SR1) assigns WINFUNC parameter is to a symbol OF, SR3) assigns <window function> to the symbol OF.

1) Let OF be the WINFUNC in an application of the Syntax Rules of this Subclause. The result of the application of this Subclause is QSX or SSSRX, as appropriate, which is returned as TRANSFORM.

2) An <aggregate function> simply contained in a <window function> shall not simply contain a <hypothetical set function>.

3) Let OF be the <window function>.

This means that the syntax element passed through WINFUNC from invoking Subclause is overwritten in SR3) and therefore WINFUNC parameter does not have any effect.

ii) The <predicate>MC LIKE PCis True if there exists a partitioning of MCV into substrings such that:

1) A substring of MCV is a sequence of 0 (zero) or more contiguous characters of MCV and each character of MCV

is part of exactly one substring.2) If the i-th substring specifier of PCV is an arbitrary character specifier, then the i-th substring of MCV is any single character.

3) If the i-th substring specifier of PCV is an arbitrary string specifier, then the i-th substring of MCV is any sequence of 0 (zero) or more characters.

4) If the i-th substring specifier of PCV is a single character specifier, then the i-th substring of MCV contains exactly 1 (one) character that is equal to the character represented by the single character specifier according to the collation of the <like predicate>.

5) The number of substrings of MCV is equal to the number of substring specifiers of PCV.

Subrule 2) and 3) provide the condition for an arbitrary character specifier in the pattern and that for an arbitrary string specifier in the pattern. Although subrule 4) must provide the condition for a sequence of single character specifiers according to classification of a substring specifier defined in GR3)c), it actually provides the condition for a single character specifier, not a sequence of them. In addition, the substring partitioning of the pattern PCV into single characters cannot make the minimum number of substring specifiers and makes maximum number of them. This means violation of GR3)c).

Incidentally, the corresponding rule to GR3)d)ii)4) in SQL:1999 is as follows:

4) If the i-th substring specifier of PCV is neither an arbitrary character specifier nor an arbitrary string specifier, then the i-th substring of MCV is equal to that substring specifier according to the collating sequence of the <like predicate>, without the appending of <space> characters to MCV, and has the same length as that substring specifier.

The symbol PORMS in 38)a) does not appear in the corresponding rule SR6)a) of Subclause 11.57, “<add overriding method specification>”, which reads:

a) If POVMS does not specify <specific method name>, then an implementation-dependent <specific method name> is implicit whose <schema name> is equivalent to SN.

SolutionModify 38)a)as follows:

a) If PORMS POVMS does not specify <specific method name>, then an implementation-dependent <specific method name> is implicit whose <schema name> is equivalent to SN.

The term “constraint” in 63)a) is different from the term at the same position on the corresponding rule to GR2)a) of Subclause 21.1,”<direct SQL statement>”, which reads:

a) A <rollback statement> or a <commit statement> is effectively executed. If an unrecoverable error has occurred, or if the direct invocation of SQL terminated unexpectedly, or if any enforced constraint is not satisfied, then a <rollback statement> is performed. Otherwise, the choice of which of these SQL-statements to perform is implementation-dependent. The determination of whether a directinvocation

T02-Annex.EIncompatibilities with ISO/IEC 9075:2008

The last sentence of item 3) is incompletely finished.Solution

Modify 3) as follows:

3) In ISO/IEC 9075-2:2008, Feature T052, “MAX and MIN for row types” provided support for MAX and MIN operations on values of row types. In this edition of this part of ISO/IEC 9075, that feature has been removed and the support provided inherently in the specification has been removed.

See comment.



The term “Feature Code” in item 7) is incorrect. The correct term is “Feature ID”.


7) In ISO/IEC 9075-2:2008, ISO/IEC 9075-4:2008, and ISO/IEC 9075-11:2008, Feature CodesIDs T322 and T332 were not used consistently; they identified three different Features in various parts of ISO/IEC 9075. In this edition of ISO/IEC 9075, three Feature CodesIDs (T322, T332, and T341) have been used consistently to identify those three Features.

11) In ISO/IEC 9075-2:2008, the length portion of a host language data structure for a CHARACTER LARGE OBJECT was measured in characters when moving from the host language to the SQL-server, but in octets in the reverse direction. In this edition of ISO/IEC 9075-2, the length portion is measured in the same units in either direction, either characters or octets, depending on the <char length units> of the declared type.

Comment (justification for change) by the MB Proposed change by the MB Secretariat observationson each comment submitted

US T02-04.01.04, Data type terminology

te There are now two conflicting definitions of array-ordered and multiset-ordered (see STR-033 and BHX-062r1).

None provided with comment.

US T02-04.15.10, Operations involving tables

te This subclause might be wordsmithed to better describe the primary effect of a data change operation on a view with an INSTEAD OF trigger. Currently we have the statement “The effect of an SQL-data change statement on a viewed table is specified by the General Rules of Subclause 15.9, “Effect of deleting some rows from a viewed table”, Subclause 15.12, “Effect of inserting a table into a viewed table”, and Subclause 15.15, “Effect of replacing some rows in a viewed table”. Which is certainly true. Then later we read “The primary effect of a <delete statement: positioned> on a regular base table T or a derived table T is to delete exactly one specified row from T. The primary effect of a <delete statement: searched> on a base table T or a derived table T is to delete zero or more rows from T.” which is not true in the case of a trigger-deletable view. Similarly for trigger-updatable and trigger-insertable-into views.


US T02-04.15.11, Identity columns

te The text describes the situation in which a value for an identity column is om9itted from the INSERT statement; however, it does not describe what happens if the INSERT statement does have a value for the identity column.

(reported by Fred Toussi, developer of an open-source SQL product)


US T02-05.03, <literal>

te GR 5) talks of "rounding or truncation" but does not say that it is implementation defined. A general hunt for “round” and “truncat” might be in order to look for all similar situations.

US T02-06.01, <data type>

te Two minor problems with <large object length>:

A) Consider the following BNF:

<length> ::= <unsigned integer>

<large object length> ::=

<length> [ <multiplier> ]

| <large object length token>

If <large object length> is omitted, then <length> is omitted and one might expect SR 5) “If <length> is omitted, then a <length> of 1 (one) is implicit” to supply the default. However SR 8) “If <large object length> is omitted, then an implementation-defined <large object length> is implicit” should be applied.

B) SR 9)a) and 9)b) hypothesize a <large object length> that immediately contains an <unsigned integer>, but actually it is <length> that is immediately contained in <large object length>

Both of these problems can be solved by revising the BNF as follows:

<large object length> ::=

<length> <unsigned integer> [ <multiplier> ]

| <large object length token>

US T02-06.01, <data type>

te SR 43) regarding <array type> says that <maximum cardinality> is the maximum cardinality of an array. It would be better to say that the value of <maximum cardinality> is the maximum cardinality.

Edit the second sentence of SR 43) as follows:

The value of the <maximum cardinality> immediately contained in AT is the maximum cardinality of a site of data type AT.

US T02-06.06, <identifier chain>

te SR 8)a)i)1) handles references to columns in the result of a <query expression>, so that they can be referenced by an ORDER BY clause. But as worded, the rule assumes

that there is a single SELECT list in the <query expression>. This ignores the possibility of UNION, etc. Probably this rule is meant to apply only to simple table queries, defined in 7.16 <query expression> SR 30)c).

US T02-06.09, <set function specification>

te SR 3) defines “aggregated argument of a <set function specification>”. A search shows that there are a few instances of “aggregated argument” applied to <aggregate function> rather than <set function specification>, namely 6.11 <nested window function> Function and SR 1), and 10.9 <aggregate function> SR 13).


US T02-06.26, <value expression>

te Consider this example:

SELECT T.C

FROM (SELECT CURRENT_DATE FROM Emp) AS T(C)

The column of the <derived table> in the FROM clause is non-determinstic, according to SR 7)a). However there is no rule that T.C in the SELECT list is non-deterministic. Note that SR 7) prolog paragraph uses general containment, but general containment does not recurse through <derived table>, <lateral derived table>, etc.


US T02-07.06, <table reference>

te SR 16)b)ii) prohibits FINAL TABLE with MERGE if the target table is a view with an INSERT or UPDATE INSTEAD OF trigger. Should there also be a prohibition if the view has an INSTEAD OF DELETE trigger? There is no new delta table for DELETE but if a MERGE fires an INSTEAD OF trigger on a DELETE then you don't know what the final delta table is; the trigger might perform an insert or update to the target view, for example.

te FINAL TABLE should be prohibited if the target table is a view that has a target underlying table that is trigger insertable-into, trigger updatable or trigger deletable, depending on the operation in the <data change delta table>.



te SR 9)b) pertains to the scope of table references in a MERGE statement. Is this statement still correct, in view of the enhancements to MERGE? For example, SR 10)b) refers to “the <search condition>” as if there were only one, but there are now three places that a <search condition> can be nested in a MERGE statement.


US T02-07.07, <joined table>

te The evaluation of a FULL outer join in GR 5)d) requires XNA, which is defined in GR 3)d), but GR 3)d) is not executed for FULL outer joins.


US T02-07.11, <window clause>

ed GR 5)b)i)1) has a probable typo “computer value” instead of “computed value”

Edit the rule as follows:

In the following subrules, when performing addition or subtraction to combine a datetime and a year-month interval, if the result would raise the exception condition data exception — datetime field overflow because the <primary datetime field> DAY is not valid for the computer computed value of the <primary datetime field>s YEAR and MONTH, then the <primary datetime field> DAY is set to the last day that is valid for the <primary datetime field>s YEAR and MONTH, and no exception condition is raised.

US T02-07.13, <query expression>

te SR 28)d)i)4) states explicitly that a common column name is regarded as fully qualified. The preceding rule SR 28)d)i)3) also talks about fully qualified column names, but does not say what to do about common column names.

Edit 30)d)i)3) as follows:

3) Let SL be the <select list> of QS. Let SLT be obtained from SL by replacing each <column reference> with its fully qualified equivalent; in the

case of common column names, each common column name is regarded as fully qualified.


te GR 5)b) and the informative note 248 that follows it assume that there is a one-to-one relationship between the result of QE and the sort table of QE. This depends on some kind of magic such as a notion of row identity. Perhaps the transformation from the sort table of QE to the result of QE by discarding columns as described in note 288 can be moved into an actual GR.



ed SR 3)i)ii)2)D)I) is structurally "P or Q and R" which is ambiguous because English conjunctions do not have a commonly agreed precedence. The rule says: "QS immediately contains a <select list> SL or TE immediately contains a <having clause> HC and SL or TE contain a <set function specification>."


US T02-08.02, <comparison predicate>

ed See minor editorial improvements to GR 1)b)ii) suggested below

Edit the lead paragraph of GR 1)b)ii) as follows:

ii) If the declared types of XV and YV are array types or distinct types whose source types are array types and the cardinalities of XV and YV are N1 and N2, respectively, then let Xi, 1 (one) ≤ i ≤ N1, denote a <value expression> whose value and declared type is that of the i-th element of XV and let Yi , 1 (one) ≤ i ≤ N2, denote a <value expression> whose value and declared type is that of the i-th element of YV. ...

3) X = Y is False if and only if one of the following is true:

A) N1 ≠ N2 or

B) N1 = N2 and for some i, 1 (one) ≤ i ≤ N1, NOT (Xi = Yi) is True, for some i.

US T02-09.16, Execution of array-returning functions

te The size of the resulting array is not always specified. The two subclauses that invoke this subclause merely create an array AR without stipulating its size. This subclause uses the variable E to keep track of which subscript to insert the next array element into. If there is no data on the open call, then AR is set to null; if there is no data on the first fetch call, then the size of AR is set to 0 elements, but otherwise the size of the output array is not set.


US T02-09.30, Determination of view component privileges

te GR 4)a)i)1) is a Case. Beneath this case, the first subrule considers a <table reference> TR that is a <table name>. Then the second subrule claims that the only other case to consider is a <query name>. But surely there are other cases. Existing TC item 3 due to SXF-020 has limited GR 4)a.0) to just updatable <query specification>s, we do not need to worry about the non-updatable kinds of <table reference> such as <collection derived table>, <table function derived table>, or <data change delta table>. But what about <only spec> and <parenthesized join table>? See SXF-020 section 1.5.


US T02-09.30, Determination of view component privileges

te GR 4)a)i)2) creates a view component privilege descriptor for the single-table DELETE case, but does not note if it is immediately dependent on any privilege.

Contrast this with GR 4)a)i)3) subrules A) and B) which handle single-table UPDATE and INSERT and handle

immediate dependencies, and with GR 4)a)ii)1) which handles the multi-table DELETE case, and handles immediate dependencies. The rules are due to SIA-018.

US T02-10.04, <routine invocation>

te According to Framework 6.3.3.8 “General Rules not terminated on exception conditions”, the GRs of this Subclause are not terminated on an exception. We should scrutinize whether that is completely true. If it is true, it would be helpful to note that fact as the first GR. If it is only partially true, we might isolate the pseudocode that does not terminate on an exception in its own subclause, with a first GR noting that the subclause does not terminate on exceptions.

Similar remarks apply to 13.4 <SQL procedure statement>, 15.19 “Execution of triggers”, and 22.1 <direct SQL statement>.



te GR 8)b)i)1)M) says that the initial value of the save area data item when invoking an array-returning or multiset-returning external function is 0. But 11.60 <SQL-invoked routine> SR 20)d)iii)8)A) says its data type is character string. The GRs of 9.16 “Execution of array-returning functions" are no help; they just say that the value on each call is copied from the value on the previous call. (Perhaps this parameter is available to the user-defined function for saving context.)



te It is not clear how SR1) and GR 1) work if the <routine invocation> is a <value expression primary>.


US T02-10.05, <character set specification

te SR 2) describes the creation of a privilege, something we normally find in a GR. Moving this rule to this subclause’s GRs would not be correct because the premise is that the privilege has already been created before this subclause

> is invoked. Perhaps this rule belongs in Concepts since this privilege is essentially a configuration issue.

US T02-11.07, <unique constraint definition>

te SR 7) says “If the <unique specification> specifies PRIMARY KEY, then for each <column name> in the explicit or implicit <unique column list> for which NOT NULL is not specified, NOT NULL is implicit in the <column definition>.” That’s fine if the <unique constraint definition> is contained in a <table definition>, but if it is contained in an ALTER TABLE statement there is no <column definition>.


US T02-11.16, <drop column not null clause>

te The GRs do not say what to do if the column is part of a primary key.


US T02-11.26, <drop table constraint definition>

te An identity column has an implicit NOT NULL constraint (11.4 <column definition> SR 16)d)) yet there is no RESTRICT or CASCADE rule about what happens to the identity column if this constraint is dropped.


US T02-11.32, <view definition>

te SR 21)r)ii)2) says that for a referenceable view whose reference type has a derived representation, the basis table shall have a candidate key that is a subset of the underlying columns of the attributes of the derived representation. This does not prevent the following scenario: basis table has candidate key (A, B) and the expression defining a column corresponding to an attribute of the derived representation is A+B. Even though the key (A, B) is unique, the value A+B is not unique, so this condition is not enough to insure that derived representations are unique, as required in 4.15.9 “Referenceable tables, subtables and supertables” penultimate paragraph.


US T02-11.32, <view

te Regarding referenceable base tables, 11.3 <table definition> SR 11)g)i) allows <scope clause> for

definition> originally-defined columns but not for inherited columns.

11.32 <view definition> SR 21)t) does not have a similar restriction. Prior to KMG-033 section 6.16 instruction 6, the GRs of <view definition> did not create column descriptors for inherited columns. Thus prior to KMG-033, the user could specify a SCOPE clause for an inherited column of a referenceable view, but nothing was done with the information. After KMG-033, the SCOPE clause is actually saved in a column descriptor. While it is correct to create column descriptors for inherited columns, it is probably not correct to allow the user to specify a SCOPE for inherited columns, since this is a variance from the

practice with referenceable base tables.

US T02-11.32, <view definition>

te GR 1)f) sets updatability in column descriptors, but there are no rules setting the indications of insertable-into or updatable in the view’s table descriptors.


US T02-11.49, <trigger definition>

te SR 15)d) says that you cannot define an INSTEAD OF trigger on a leaf underlying table of a view that specifies WITH CASCADED CHECK OPTION. But does this recurse deep enough? Don't we want to prohibit it on a view that is a generally underlying table of a view WITH CASCADED CHECK OPTION?


US T02-11.49, <trigger definition>

te INSTEAD OF trigger on a view V should be prohibited if there is a schema object dependent on V that performs a <data change delta table> that specifies FINAL TABLE that targets V, since the FINAL TABLE becomes illegal if the INSTEAD OF trigger is defined. SQL routines and triggered actions are two such categories of schema objects.


US T02-11.49, <trigger

te SR 7)f) defines the scope of the old and new transition table and variable names to be <triggered action>. This

definition> means that they are not in scope in the <triggered when clause>. But in that case there is no way to evaluate the <search condition> in the <triggered when clause>, as required by 15.19 “Execution of triggers” GR 4)b)i).

US T02-11.60, <SQL-invoked routine>

te SR 20)g) checks that the <data type> of an effective parameter is supported by the host language of an external SQL-invoked routine. In the case of an SQL-invoked function with PARAMETER STYLE SQL, the return type is converted into an OUT parameter in the effective parameter list by SR 20)d)iii)2) so the return type is checked against the supported types of the host language. However, for an external SQL-invoked routine with PARAMETER STYLE GENERAL, the return type is never checked against the supported types of the host language.


US T02-11.60, <SQL-invoked routine>

te SR 6)n)i) says “A <result cast from type> is specified that simply contains an <array type> or a <path-resolved user-defined type name> whose source type is an array type and does not contain a <locator indication>.” This is ambiguous because the English conjunctions “and” and “or” do not have commonly understood precedence. SR 6)n)ii), 6)o)i) and 6)o)ii) have the same problem.


US T02-12.01, <grant statement>

te GR 4)e) contains a case with two subrules i) and ii) but no “otherwise”. This means that there are cases in which WGO is not defined. Perhaps the REFERENCES privilege should not be granted if neither i) nor ii) applies.


US T02-12.02, <grant privilege statement>

te GR 7), 8) and 9) use <action> in a sloppy fashion. Elsewhere it is clear that an <action> with a <column name list> such as SELECT (C1) is not the same as an <action> without a <column name list> such as vanilla SELECT. What these rules intend to do is construct, e.g., SELECT (C1) as an <action> from the different <action> of SELECT, rather than use “the identical <action>”. We

should also check other places that construct column or table/method privileges from table privileges.

US T02-12.07, <revoke statement>

te GR 5)a) uses the view privilege dependency descriptors to determine the direct dependencies of DML privileges on views. The dependency descriptors are created in 9.29 "Determination of view privileges" and 9.30 "Determination of view component privileges". However, those subclauses only compute the privileges of a view based on its view definition and result in view privileges with the special grantor _SYSTEM. This works for the definer of the view but not for anyone who is subsequently granted access to the view..


US T02-14.12, <merge statement>

te GR 6)a)i)1) assumes that the range variable for the target table is a <table name>, ignoring the fact that the BNF and Syntax Rules permit a correlation name.



te GR 6) lead paragraph appears to specify a loop over all <merge when clause>s. However, the subrules do not adhere to this strictly. In particular:

GR 6)a) appears to handle a single <merge when matched clause>. Its subrule ii) identifies a set of rows as the old delta table of merge operation. However, the old delta table must be the union across all <merge when matched clause>s, so it should not be subordinate to processing a single <merge when matched clause>.

GR 6)b) appears to handle a single <merge when not matched clause>. Subrules i) through vii) can certainly only handle a single <merge when not matched clause>. However, subrule viii) needs to form the union of the candidate rows from each <merge when not matched

clause>.

For both of these, it would be better to have an explicit loop to do the processing of individual <merge when matched clause>s or <merge when not matched clause>, followed by separate rules after the loops to perform the unions.


te CR 1)a) talks of an underlying table that is broadly contained in a piece of syntax. What must be meant is an underlying table specification. This was not fixed by KRK-021; maybe there are similar rules with the same problem.



te GR 6)b)iv) assumes that a <table or query name> can be used as a correlation name. This is not true if the <table or query name> is a <table name>..


US T02-14.15, <set clause list>

ed GR 1) says “A <set clause> specifies one or more object columns and an update value.” But in fact, if there is more than one object column, then there is more than one update value.

Edit GR 1) as follows:

1) A <set clause> specifies one or more object columns and an equal number of update values. An object column is a column identified by an <object column> in the <set clause>. The An update value is the value specified by the an <update source> contained in the <set clause>.

US T02-15.12, Effect of inserting a table into a viewed table

te GR 3)a) handles INSTEAD OF INSERT triggers. There is no check for either CASCADED CHECK OPTION or LOCAL CHECK OPTION (unlike GR 3)b)). This is correct in the case CASCADED CHECK OPTION, but what about LOCAL CHECK OPTION? See 11.49 <trigger definition> SR 15)c). The paper that introduced this is

URC-033. Note that section 1.1 PDF page 4 item 6 says “WITH CHECK OPTION must not have been specified for the view”. Possibly the paper meant to prohibit both kinds of CHECK OPTION. Or possibly it meant to prohibit CASCADED CHECK OPTION (the default) but forgot to include the rules to enforce the LOCAL CHECK OPTION. This is also an issue 15.15 “Effect of replacing some rows in a viewed table”.

US T02-20.01, Description of SQL descriptor areas

te SR 3) describes how LEVEL is used to indicate subordinate descriptor areas, but it does not state what the value of LEVEL is for a “top-level” SQL item descriptor. Presumably it is 0, based on the initialization in 20.2 <allocate descriptor statement> GR 3)b). It would be helpful to the reader to clarify this in 20.1 “Description of SQL descriptor areas”.


US T02-20.02, <allocate descriptor statement>

te GR 2) last sentence says "The maximum number of SQL descriptor areas that can be allocated at one time is implementation-defined." However, <occurrences> does not specify the number of SQL descriptor areas, it specifies the number of SQL item descriptor areas (see GR 3)b)). Annex B says that both the maximum number of SQL descriptor areas and SQL item descriptor areas are implementation-defined.


US T02-20.06, <prepare statement>

te Most of the subrules of GR 5)a) that identify exact numeric data types with scale 0 use NUMERIC (MP, 0); however, a few use INTEGER and a few use NUMERIC (MP). It might be better if they all used the same data type.


US T02-21.04, <embedded SQL C program>

te <C NCHAR variable> permits an optional <character set specification>. According to SR 4)b)i), this declaration corresponds to a <host parameter data type> that is NATIONAL CHARACTER with the user-specified character set. However, NATIONAL CHARACTER type

latter because of <C array locator variable> and <C multiset locator variable>. So presumably this means a scalar C type. But then, what about <C BINARY variable> and <C REF variable>, which are transformed into array of char? And what about <C BLOB variable>, which is transformed into a struct? Maybe we can just delete this rule, if the BNF and the transformations already insure that the C declarations are correct.
