RE: Sqlcod question

I'm under the impression that you usually only use DECLARE CURSOR if
you're going to do a FETCH. Otherwise, there are other ways to determine
the absence or presence of a record in a single SQL statement, such as
SELECT 1 FROM xxx WHERE..
Or SELECT COUNT(*) FROM...

Adding fetch took care if the problem thanks I was hoping to avoid the
multiple calls but oh we'll :)

SQLER3 also returns the row count I believe.

Because the statement completed successfully with no errors. Use

I have the following embedded code:

Exec SQL
Declare C1 cursor for
Select * from rates
Where opcode =:zcode;
Exec SQL open C1;

Now I know for a fact that there will not be a match right now

meaning

that the value of zcode is not in the file.....so why does Sqlcod

return

all zeros?
