Master - detail datawindow

Hi all,

I have 2 tables in a master - detail relationship.

I want to create a datawindow where all the records from master table A are shown, and possible records from detail table B.

When there's no detail record in table B, i still want to show the master record from table A.

I've been playing around with the LEFT JOIN and UNION solutions , but the way i created my sql , results in a slow retrieval of the datawindow.

Any tips or idea's on how to accomplish this please ?

TIA

John
