Re: Error in 'psqlodbca.dll'

Do other queries work, and only this one gives the error? What happens
if you did a query with a where conition that returned only 10 rows,
would you still get the error? Also I'm not much of a Delphi programmer,
but I have an idea of what ADO code should look like, could you post the
code snipit in question?
