Copy from one column to another (different tables same database) in MySQL?

To copy from one column to another, you can use INSERT INTO SELECT statement.

Let us first create a table −

mysql> create table DemoTable1 (PlayerScore int);
Query OK, 0 rows affected (0.46 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1 values(98);
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable1 values(81);
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable1 values(76);
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable1 values(88);
Query OK, 1 row affected (0.15 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable1;

This will produce the following output -

+-------------+
| PlayerScore |
+-------------+
| 98          |
| 81          |
| 76          |
| 88          |
+-------------+
4 rows in set (0.00 sec)

Here is the query to create a second table −

mysql> create table DemoTable2 (Marks int);
Query OK, 0 rows affected (0.47 sec)

Here is the query to copy from one column to another (different tables same database) MySQL −

mysql> insert into DemoTable2(Marks) select PlayerScore from DemoTable1;
Query OK, 4 rows affected (0.19 sec)
Records: 4 Duplicates: 0 Warnings: 0

Display all records from the table using select statement −

mysql> select *from DemoTable2;

This will produce the following output -

+-------+
| Marks |
+-------+
| 98    |
| 81    |
| 76    |
| 88    |
+-------+
4 rows in set (0.00 sec)
