How to clone a MySQL table, indexes, and data?

To clone a MySQL table, indexes and data, we can use “LIKE”. I have a database ‘business’ and in that many tables have been created. Here we can check all the tables.

mysql> USE business;
Database changed

Let us display all the tables −

mysql> SHOW tables;

| varcharurl             |
| whereconditon          |
+------------------------+
63 rows in set (0.25 sec)

Now, I am using the table STUDENT from the above database. The query is as follows −

mysql> DESC student;

The following is the output

+-------+--------------+------+-----+---------+-------+
| Field | Type         | Null | Key | Default | Extra |
+-------+--------------+------+-----+---------+-------+
| id    | int(11)      | YES  | MUL | NULL    |       |
| Name  | varchar(100) | YES  | MUL | NULL    |       |
+-------+--------------+------+-----+---------+-------+
2 rows in set (0.20 sec)

Let us now check the records of the student table:

SELECT * from student

Here is the output:

+------+------+
| id   | Name |
+------+------+
| 1    | John |
| 2    | Bob  |
+------+------+
2 rows in set (0.00 sec)

Here is the query; we can make clone of indexes as well as data using LIKE. The query is as follows −

mysql> CREATE table cloneStudent like student;
Query OK, 0 rows affected (1.57 sec)

mysql> insert cloneStudent SELECT *from student;
Query OK, 2 rows affected (0.60 sec)
Records: 2 Duplicates: 0 Warnings: 0

Therefore, I have successfully created clone as well as data. Now, we can prove that we have created clone of indexes as well as data with the help of DESC command, which is as follows −

mysql> DESC cloneStudent;

The following is the output

+-------+--------------+------+-----+---------+-------+
| Field | Type         | Null | Key | Default | Extra |
+-------+--------------+------+-----+---------+-------+
| id    | int(11)      | YES  | MUL | NULL    |       |
| Name  | varchar(100) | YES  | MUL | NULL    |       |
+-------+--------------+------+-----+---------+-------+
2 rows in set (0.00 sec)

Let us check whether the table is cloned or not.

mysql> SELECT * from cloneStudent;

The following is the output:

+------+------+
| id   | Name |
+------+------+
| 1    | John |
| 2    | Bob  |
+------+------+
2 rows in set (0.00 sec)
