Sorry, Vern's right...

Mine would give an 'X' if there was _NO_ match in B.

Here's what I want to do...TableA has 4 columns. TableB shares a key value
with TableA. I want to produce this output in a select statement (to be
used from PHP fwiw):

TableA.Fld1 TableA.Fld2 'X' (if TableA.Fld1 is in TableB).

I've been trying combinations of a CTE, CASE, and exists, but I can't get
this to work. I'd like:

A1 A2
A3 A4 X
A5 A6 X
A7 A8

IOW, I want the values for TableA to show up, and an X if the
corresponding
key value is in TableB. This has to be easier than I'm making it out to
be.

Thanks!
