Simplest way to copy data from one table to another new table in MySQL?

To copy data from one table to another table, firstly we will create a table.

Creating first table −

mysql> CREATE table FirstTable
-> (
-> id int,
-> name varchar(100)
-> );
Query OK, 0 rows affected (0.61 sec)

After creating a table, we will insert records.

mysql> INSERT into FirstTable values(1,'john');
Query OK, 1 row affected (0.20 sec)

mysql> INSERT into FirstTable values(2,'Smith');
Query OK, 1 row affected (0.21 sec)

We can display all the records with the help of SELECT statement −

mysql> SELECT * From FirstTable;

The following is the output

+------+-------+
| id   | name  |
+------+-------+
| 1    | john  |
| 2    | Smith |
+------+-------+
2 rows in set (0.00 sec)

Now, I am creating second table and I will copy the first table data into the second table. Creating second table −

mysql> CREATE table SecondTable
-> (
-> id int,
-> name varchar(100)
-> );
Query OK, 0 rows affected (0.69 sec)

Here is the query to make a copy −

mysql> INSERT INTO SecondTable (id,name)
-> select id,name from FirstTable;
Query OK, 2 rows affected (0.17 sec)
Records: 2 Duplicates: 0 Warnings: 0

To check that the record is copied or not, we can check the secondTable with the help of SELECT statement −

mysql> SELECT * from SecondTable;

The following is the output

+------+-------+
| id   | name  |
+------+-------+
| 1    | john  |
| 2    | Smith |
+------+-------+
2 rows in set (0.00 sec)
