Q: Delete subselect

--part1_111.26c6889e.2c6d6bdf_boundary
Content-Type: text/plain; charset="US-ASCII"
Content-Transfer-Encoding: 7bit

I know that MySQL 3.23.nnn did not support a delete subselect, just wondering
what the best/most efficient way to do the following is:

delete from table_a where table_a.column_1 in ( select column_1 from
table_b);

Assuming that column_1 is the same data type and size in both table_a and
table_b.

Any help would be greatly appreciated.

Regards,
Tony
