How To Insert Multiple Rows with One INSERT Statement?

If you want to insert multiple rows with a single INSERT statement, you can use a subquery instead of the VALUES clause. Rows returned from the subquery will be inserted the target table. The following tutorial exercise gives a good example:

mysql> INSERT INTO fyi_links SELECT id+500, REVERSE(url), 
   notes, counts, created FROM fyi_links;
Query OK, 5 rows affected (0.01 sec)
Records: 5  Duplicates: 0  Warnings: 0

mysql> SELECT id, url, notes, counts, DATE(created) 
   FROM fyi_links;
+-----+-------------------+-------+--------+---------------+
| id  | url               | notes | counts | DATE(created) |
+-----+-------------------+-------+--------+---------------+
