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...

You have to FETCH the resulting dataset into a variable to see if the
SQL returned any data.

Subject: Sqlcod question

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?
