Re: Problem with PHP and PostgreSQL

But were you pointing at the result handle or the query string when you
ran pg_num_fields?

This won't work:

$conn = pg_connect("dbname=bigdb host=myserver user=me2");
$query_panels = sprintf("SELECT... ;
$res = pg_query($conn,$query_panels);
$fieldcount = pg_num_fields($query_panels); <-- Notice I put the query
there, not the result handle...
