I know that this response was directly related to a question about
subqueries, but I think it's important to point this out, because I almost
didn't pursue this avenue as a result.
As Fred pointed out, MySQL does not support IN and NOT IN, but *only* in the
case of subqueries:
select * from table 1 where id in (select id from table2)
However, it DOES support IN and NOT IN as long as a subquery is not used:
select * from table 1 where id in (115,515,614,23,51,24,15,12,51,23)
I still find I use the IN and NOT IN quite frequently, though it would be a
whole lot more efficient with subqueries (which I believe are coming with
version 4?)
