A further extension of this.. What might I be able to additionally order by so that the most recently updated rows get ordered above everything else (within the order by ordernum).. Using the same example : > ordernum | fieldname | oid > ----------+---------------+--------- > 1 | J.jobtitle | 1197126 > 1 | J.inv_id | 1197125 > 2 | J.updatedon | 1197127 > 3 | J.empinitials | 1197128 I just set the row with j.inv_id to 1, I'd like it to be ordered above the row with j.jobtitle in it -- is that possible?
