Microsoft's ActiveX Data Objects - their most popular and recommended non-dotNET data access libraries. If they break, wewill certainly get lots of bug reports :-(. My app is pretty basic as well, so it's unlikely to be an edge case. Oh, andfwiw, it's worked with psqlODBC back to v6.something, so it's not simply that it gets confused now it sees a rowcountfrom a select 'cos it always used to :-) /D -----Unmodified Original Message----- I'm not sure how I'd investigate such an issue.

Unfortunately, ADO doesn't give any useful error messages. I'm not entirely sure what's wrong - can you look at it please? I'm still swamped at the moment :-( Regards, Dave > -----Original Message----- > From: pgsql-odbc-owner@postgresql.org > [mailto:pgsql-odbc-owner@postgresql.org] On Behalf Of Dave Page > Sent: 15 September 2005 09:12 > To: Scot Loach; pgsql-odbc@postgresql.org > Subject: Re: [ODBC] row count with libpq driver > > > > > -----Original Message----- > > From: Scot Loach [mailto:sloach@sandvine.com] > > Sent: 15 September 2005 04:02 > > To: Dave Page; pgsql-odbc@postgresql.org > > Subject: RE: [ODBC] row count with libpq driver > > > > A patch for this is attached, please review. > > Thanks Scot - patch applied with a couple of minor fixes - > specifically > > +#ifndef USE_LIBPQ > + if (res->recent_processed_row_count = 0 && > res->ntuples > 0) > + { > + *pcrow = res->ntuples; > + return SQL_SUCCESS; > + } > +#endif > > Was changed to > > +#ifdef USE_LIBPQ > + if (res->recent_processed_row_count == 0 && > res->ntuples > 0) > + { > + *pcrow = res->ntuples; > + return SQL_SUCCESS; > + } > +#endif > > Note the '#ifdef', and '== 0' > > Regards, Dave > > ---------------------------(end of > broadcast)--------------------------- > TIP 6: explain analyze is your friend >
