How To Create a New Table by Selecting Rows from Another Table in MySQL?
✍: FYIcenter.com
Let's say you have a table with many data rows, now you want to create a backup copy of this table of all rows or a subset of them, you can use the "CREATE TABLE ... SELECT" statement. The tutorial script below gives you a good example:
mysql> INSERT INTO tip VALUES (1, 'Learn MySQL', 'Visit dev.fyicenter.com','2006-07-01'); Query OK, 1 row affected (0.62 sec) mysql> CREATE TABLE tipBackup SELECT * FROM tip; Query OK, 1 row affected (0.49 sec) Records: 1 Duplicates: 0 Warnings: 0 mysql> SELECT * FROM tipBackup; +----+-------------+-------------------------+-------------+ | id | subject | description | create_date | +----+-------------+-------------------------+-------------+ | 1 | Learn MySQL | Visit dev.fyicenter.com | 2006-07-01 | +----+-------------+-------------------------+-------------+ 1 row in set (0.00 sec)
As you can see, this SQL script created a table called "tipBackup" using the same column definitions as the "tip" table and copied all data rows into "tipBackup".
