SQL Delete from table where rows found in a join

Hi,

I want to update and delete using the result of a join. If I create a table first containing the rows to modify can I safely join to it for the update or delete?

Like so :

Get lines to delete/update.
CREATE TABLE qtemp/RRN as (
with t as (
select statement)

select rrn(a) rrn from myfile a join t on
join conditions )

with data


Followed by :

Delete from myfile where rrn(myfile) in (select *from qtemp/rrn).

Maybe there's an easier way?
