Ans. IF(VSAL<10000) THEN VBONUS :=VSAL*(10/100); ELSIF(VSAL BETWEEN 10000 AND 20000) THEN VBONUS :=VSAL*(20/100); ELSIF(VSAL BETWEEN 20000 AND 25000) THEN VBONUS :=VSAL*(25/100); ELSIF(VSAL >25000) THEN VBONUS :=VSAL*(30/100); END IF; DBMS_OUTPUT.PUT_LINE(VBONUS);-- BONUS :=VBONUS;END CALCULATE_BONUS;

T_F_NAME TEACHER.F_NAME%TYPE; T_SALARY TEACHER.SALARY%TYPE; TAX TEACHER.SALARY%TYPE; CURSOR CURR IS SELECT F_NAME,SALARY*12 FROM TEACHER; BEGIN OPEN CURR; LOOP FETCH CURR INTO T_F_NAME,T_SALARY ; EXIT WHEN CURR%NOTFOUND; IF T_SALARY<100000 THEN TAX:=0; ELSIF T_SALARY<150000 THEN TAX:=(T_SALARY-100000)*0.20; ELSIF T_SALARY<250000 THEN TAX:=(T_SALARY-150000)*0.30+50000*0.20; ELSE TAX:=(T_SALARY-250000)*0.40+100000*0.30+50000*0.20; END IF; DBMS_OUTPUT.PUT_LINE(T_F_NAME||' OWES '||TAX||' AS TAX '); END LOOP; CLOSE CURR; END;

7) In all the embedded SQL program segments that you have created so far for the University and Bank database system, create suitable error handling features.

Ans. CREATE OR REPLACE PROCEDURE FINDTEACHER(TEACH IN VARCHAR2)ISC_T_NO TEACHER.T_NO%TYPE;CNT NUMBER :=0;CURSOR CURR ISSELECT T_NO FROM TEACHER WHERE F_NAME=TEACH;BEGIN OPEN CURR; FETCH CURR INTO C_T_NO; IF CURR%NOTFOUND THEN DBMS_OUTPUT.PUT_LINE('THE TEACHER YOU ENQUIRED DOES NOT EXIST');
