Re: subselect in 'IN list', Win2000, mysql 4.1.7
Difference is in way how it is executed.
Subquery will be executed for every row of outer query (now). We have plans to change it (optimize IN subqueries for case like you have) but it is not done yet.
So now in this case you better use join if you can.
