Re: Help With complex SELECT

OK, I am close.

Here is what I have

SELECT a.*,b.* from employees as a LEFT JOIN statentry as b ON
a.uid=b.uid
WHERE b.timestamp IN (select MAX(timestamp) from statentry where
uid=b.uid)
OR b.timestamp IS NULL


This returns me all the values, but for some rease UID in the result
set is allways null. ANy idea why?

THanks,
-SJ
