Re: [GENERAL] Getting total records in result set

What is the easiest (and least system intensive) method of getting the total number of records in the result set? I am presently opening the cursor, doing a FETCH ALL, reading PQntuples(), closing the cursor, and reopening it for the 'real' work. Background: I am writing a CGI script that paginates the output from an SQL query and need to know a total number of records to calculate the number of pages to display. Is what I am going correct or is there a better way? Thanks, Mike. ====================================================================== Mike Frisch Email: mfrisch@saturn.tlug.org Northstar Technologies WWW: http://saturn.tlug.org/~mfrisch Newmarket, Ontario, CANADA ======================================================================
