54 | 5.3 Functionality missing from MySQL
55 |
56 | The following functionality is missing in the current version of MySQL. 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. Try using a LEFT JOIN to do the "NOT IN"/ "MINUS" equivalent.
