Hi All,

I need a optimised query , which selects and stops when one row satisfying the given condition say for example emp_salary>10000 is met.
The query should not proceed further.
I need this query in order to reduce the DB2 cost and improve performance.

Thanks & Regards,
Yogesh.

If you use

Code:


FETCH FIRST 1 ROWS ONLY



at the end of your query should satisfy your requirement .

If this is not what you need, please explain further.
