RE: Filling a Subfile with an SQL statement / Writing a CSV

Brian,

If you are going to get more than one record with SQL, you *have to* use
a cursor. You should check the value of SQLSTT to control your loop (you
can use SQLCOD but SQLSTT is the recommended practice). If a FETCH was
successful, SQLSTT will start with 00 or 01 (SQLSTT's that start with 01
are informational messages that can generally be ignored). Your program
will be something like this (note that this is more pseudo code than
real code):

- DECLARE CURSOR
- OPEN CURSOR
- While SQLSTT starts with 00 or 01
  - FETCH FROM CURSOR
  - do stuff
- CLOSE CURSOR

Also, if you go the CSV route, you should be aware that Excel does not
handle CSV files correctly. Specifically, if you have a numeric looking
field that starts with zeros, Excel will drop the leading zeros even if
you enclose the value in double quotes (this causes lots of problems
with things like ISBNs). There is an escape character you can add to
prevent this from happening in Excel but I don't recall what it is.

Thanks.  My only question is how do you move forward in the recordset?
I'm assuming if you are writing the results, you would need to be able
to go through the results one by one, correct?

Hi Brian,

...and for the first question you can test SQLCOD, ie, DoW SQLCOD = 0

Hope this helps,

G4!
