FILTERS and FUNCTIONS FILTERs

TWO Types of FiltersVisible

Stored in Master FileActivated by reference in a request

InvisibleIndependent command Executable in PROFILEs, or FOCEXECsActive for the entire sessionAdded to every request using the Master

FILTERS and FUNCTIONSVisible FILTERs

What is a visible FILTER?Virtual Field stored in Master File.

Must evaluate to True or False – 1 or 0.Format is always I1.

Only evaluated when referenced in your request. Functional with

CHECK FILETABLE/TABLEF FILEMATCH FILEMORE SQL

FILTERS and FUNCTIONSVisible FILTER

Visible FILTER syntax

FILTER <filtername> = expression;$

Positioned anywhere in Master.Use any expression legal for WHEREUsable with Business View or Join.Shortest unique truncation will access it.FILTER TOPSELLERS = SALES GT 20000;$


ExpressionsWHERE (expression) (operator) (expression) AND/OR …

(field/literal/function) (operator) (field/literal/function)

Each expression has one or more operators Can use real and virtual fields in the Master file.Cannot use virtual fields created in the request or fields described

in other files.Selections based on fields from multiple files must be AND/OR in

the WHERE phrase – not in the FILTER. IF..THEN..ELSE and DECODE to Alpha are not supported in

FILTERs.


Referencing Visible FILTERs

WHERE <filtername>

No limit to the number of Filters.FILTER from Master File is automatically included on

reference in request.Beware collisions– multiple WHEREs are ANDed

together. From Master and Request!Be precise not creative with the Filter Names –

indicate what it does.


Filter NamingThink of your endusers and how they see the data!Combine complex selection criteria into one filter!Give the filter a meaningful name!

FILTER1 – probably uselessFROMLASTWEEK - better


Examples

REVIEW4RAISE = HIRE_DATE LT 810101

AND CURR_SAL LT 12500

AND CURR_JOBCODE CONTAINS ‘A’;$

REVIEW4RAISE = HIRE_DATE LT 810101

FILTERS and FUNCTIONSInvisible FILTERs

What is an invisible FILTER?

And how is it different from a visible FILTER?Activated anywhere in session. Not referenced in request.Controlled with commands

Declared with FILTER FILE command.Activated/Deactivated with SET FILTER command.Requires SET KEEPFILTERS to cross JOINsStatus of FILTER can be queried -? FILTER.

Supports Defines available only to FILTERs.Allows both WHERE and IF syntax.

FILTERS and FUNCTIONSFunctions

The Path to FUNCTIONSVirtual fields are linked to Master File or Synonym

DEFINE

COMPUTE

RECAP

Often contain logic common to many fields

Reformating dates, names, times

Calculating standard comparison – margin, percent

Use DEFINE FUNCTION to make that logic reusable

DEFINEd FUNCTIONS - callable like IB functions

DEFINEd FUNCTIONS - independent of Master File


The Uses of FUNCTIONSStandardizing

Corporate business logic

FOCUS/WebFOCUS coding standards

Simplifying

Complicated groups of expressions

Repeated groups of expressions

Creating

New subroutines currently unavailable

Customization of existing functions

Based on the FOCUS/WebFOCUS language


The Syntax of FUNCTIONS - 1

DEFINE FUNCTION name (argument1/format,…argumentn/formatn)[tempvariablea/formata = expressiona;]..[tempvariablen/formatn = expressionn;]name/format = [result_expression];END


Name of function.Last field calculated in function.Returns value to calling procedure.

Name of function.Last field calculated in function.Returns value to calling procedure.

Arguments and formats that are used when the function is called.Fields actually used in call must match the type indicated – alpha or numeric. Alpha

Too short – padded with spacesToo long – truncated

Intermediate fields use in calculation of final result. Unlimited numberUse argments, constants and other temporary fields declared in the function.

Using DEFINEd FUNCTIONS

DEFINE Functions can be called by other DEFINE Functions.

DEFINE FUNCTION Unlimits

Number of Functions used in session

Number of arguments used in a function.

DEFINE FUNCTION Limits

Can not call themselves.

Names must be 8 characters or less.

Argument names must be 12 characters or less.
