Dear David

Acutally, I want to display the maximum number of record in the result of execute query list will be limited by 500.

for example when i enter the critria there may populate the records more then 5000. but I want only show first 500 records rest will not display in the result and more over there should be a information for displayed record = 500. This is requirement to imrove the perforamce of form.

Wait for your soluation

Well, I'd rather test forms' behaviour by setting the "Query Array Size" and "Number of Records Buffered" data block properties.

I agree with Littlefoot. Consider using different values for the 'Optimizer Hint' property of the block, for example, 'first_rows'.

you can try typing the following SQL query:

query:
-------------------------------
SELECT EMPNO,EANME FROM EMP
HAVING MAX(ROWNUM)<=5
GROUP BY EMPNO,ENAME,SAL ORDER BY SAL DESC
------------------------------

output:

EMPNO ENAME
------ ----------
7566 JONES
7499 ALLEN
7654 MARTIN
7521 WARD
7369 SMITH

thank you.

Note: at line no. 2 you can
put 500 or whatever instead of 5
as per your populating requirement.
