Re: Delete with an inner join

[Michael_Schutte@xxxxxxxxxxxx]

Look into the WHERE EXISTS clause.  You cannot do a join on a delete
statement.  So instead you put the joined files into a where exists clause.

ie.

delete from filea a
where exists(select '1' from fileb b join filec c on b.key = c.key where
a.key = b.key)
 and ... -- other where conditions
