Hi,
I have written a CURSOR to find the entered branch in perticular date is available or not its working fine through which
if found I am delete the old records and inserting new records
else
insert new records
Example:
CURSOR
SELECT...
BEGIN
OPEN...
IF idate=:vdate and ibranch=:vbranch then
delete from sales where idate=:vdate and ibranch=:vbranch
INSERT INTO SALES
SELECT * FROM ITEMMAST
commit;
else
INSERT INTO SALES
SELECT * FROM ITEMMAST
commit;
END IF;
The above Cursor is taking very very long time to process and display in the form.
Please tell me how to increase performance.
Thanks,
Syed Muzzammil.

Instead of INSERT INTO SALES SELECT * .... Try
INSERT INTO SALES SELECT COL1,COL2.....
Commit can appear once after the end if statement.
Your code can be like this also
IF idate=:vdate and ibranch=:vbranch then
delete from sales where idate=:vdate and ibranch=:vbranch
END IF;
INSERT INTO SALES
SELECT col1,col2 FROM ITEMMAST
commit;
