I query SELECT usename FROM pg_user WHERE usename ~* 'star_.*'; in the psql command line. I get a result in the command line, but not one when I do the same query in jdbc. It seems to screw up when I do a WHERE query. I am only expecting 1 result to come back, but in the java code as seen below, the rs is empty. So rs.next() == false. ResultSet rs; rs = null; rs = this.executeQuery(SELECT usename FROM pg_user WHERE usename ~* 'star_.*')l CarrotData.instance().assert("this i cannot allow (having a null ResultSet)!", rs != null); while (rs.next()) { ret.addElement(rs.getString("usename")); } } catch (SQLExceptione) { CarrotData.instance().error(e); } Thanks Matt Peter Mount wrote: > Probably the backend.
