Hi, I'm executing a query through psql ODBC which is taking around 2 minutes
to complete. When I run it from PgAdmin it takes less than 3 seconds.
The query itself has :
. 15 inner joins (from just around 10 different tables - the other inner
joins are using different aliases for the same tables)
. Select statement returns 1 field.
. the testing database is selecting only 1 record.
Taking a look at the explain analyze report, I see they are both quite the
same and tested the ODBC driver through Visual Foxpro and Vb.NET as well,
taking both around 2 minutes to finish.
Any idea ?
Thanks,
Sebastian
