Hello I asked something similar to this in the past, but even with the previous answer, this slight variation has me stumped (not hard to do) TableA A_ID integer Text varchar(100); TableB B_ID integer A_ID integer Price integer Changed TIMESTAMP For every A_ID, I'd like the latest price (deduced by 'Changed') from Table_B. There could be multiple(or zero) entries for A_ID in TableB. I need the following columns: A.A_ID, A.Text, B.Price, B.Changed where B.Price, B.Changed are the most recent entry in Table B. I can guess that the query should have a max and possibly some 'group by' statements, but it's knowing where to put them. Any hints greatly appreciated. TIA David
