Re: Faster key lookup

was going to suggest "fetch first row only". But that still does the
count. The first row is that of the output. Which is the count itself.

I would fetch first row only into a field with a nullable indicator.

Maybe upgrade to a faster system?

I have a *SRVPGM that calls a procedure a lot, and I need to speed it up.

Here's the entire code for the procedure:
EXEC SQL
Select count(*)
Into :rc
From MY_TABLE
Where COLUMN1 = :local1 and COLUMN2 = :local2 and COLUMN3 = :local3
And (COLUMN4 = :local4 or :local4 = '');
Return (SQLSTATE = '00000' and rc > 0);
