Byron,
How I can know the number of rows in the set after a _select_
(ie SQLRowCount isn't valid here) statement using ODBC ?
TIA,
Sergio

Actually, it is valid, and will return the number of rows in the result
set, but only if you are *NOT* using the "Declare/Fetch" option of the
driver.

Very good information, thanks.
Now suppose that I don't know if the user is using declare/fetch,
I have another option ?

SQLRowCount returns -1, which is what the odbc spec says to return if the
driver doesnt know the count.
