For a prioritized list indicating when new extensions may be added to MySQL, you should consult the 57 | online MySQL TODO list. That is the latest version of the TODO list in this manual. See section F List of things we want to add to MySQL in the future (The TODO). 58 | 59 | 5.3.1 Sub-selects 60 | 61 | The following will not yet work in MySQL: 62 | 63 | SELECT * FROM table1 WHERE id IN (SELECT id FROM table2); 64 | SELECT * FROM table1 WHERE id NOT IN (SELECT id FROM table2); 65 | 66 | However, in many cases you can rewrite the query without a sub select: 67 | 68 | SELECT table1.* FROM table1,table2 WHERE table1.id=table2.id; 69 | SELECT table1.* FROM table1 LEFT JOIN table2 ON table1.id=table2.id where table2.id IS NULL 70 | 71 | For more complicated sub queries you can create temporary tables to hold the sub query. 72 | 73 | MySQL only supports INSERT ... SELECT ... and REPLACE ... SELECT ... Independent sub-selects will be probably be available in 3.24.0. You can now use the function IN() in other 74 | contexts, however. 75 | 76 | --- end snip --- 77 | 78 | Ie.
