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)
