The following will not yet work in MySQL:













MySQL currently only supports sub selects of the form @code{INSERT













... SELECT ...} and @code{REPLACE ... SELECT ...}. You can however use













the function @code{IN()} in other contexts.

























In many cases you can rewrite the query without a sub-select:





























@example















SELECT * FROM table1 WHERE id IN (SELECT id FROM table2);













@end example

























This can be re-written as:

























@example













SELECT table1.* FROM table1,table2 WHERE table1.id=table2.id;













@end example

























The queries:

SELECT * FROM table1 WHERE id NOT IN (SELECT id FROM table2);















SELECT * FROM table1 WHERE NOT EXISTS (SELECT id FROM table2 where table1.id=table2.id);
