Re: question about NOT IN

["Jason Landry" <spamsink@xxxxxxxxxxxxx>]

Subqueries like that won't work until version 4.0.

for now it's rather ugly and inefficient, but one way you could do it would
be like this:

select table1.*, ifnull(table2.column2,-1) as marked from table1 left join
table2 on table1.column1=table2.column2 having marked=-1

I've done something similar before, and it worked ok.  Of course having
subqueries will be nice.
