OK - I see that it works now - which is great! However, it's unclear to me what, exactly, it is that is "TRUE"? What am I joining to what? The syntax is unclear to me - if I'm joining, I should be joining on tab_A.field_x = tab_B.field_y - no? Why does SQL Server's OUTER APPLY not require this? Thanks for any input - Merci, À+ Rgs, E.
