Easiest way to copy values of one column to a new table in MySQL?
For this, use AS select statement. Let us first create a table −
mysql> create table DemoTable1 ( Score int ); Query OK, 0 rows affected (1.22 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1 values(89); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable1 values(98); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable1 values(91); Query OK, 1 row affected (0.24 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable1;
This will produce the following output −
+-------+ | Score | +-------+ | 89 | | 98 | | 91 | +-------+ 3 rows in set (0.00 sec)
Following is the query to copy values of one column to a new table −
mysql> create table DemoTable2( StudentScore int )AS select Score AS StudentScore from DemoTable1; Query OK, 3 rows affected (0.81 sec) Records: 3 Duplicates: 0 Warnings: 0
Let us check the table records once again −
mysql> select StudentScore from DemoTable2;
This will produce the following output −
+--------------+ | StudentScore | +--------------+ | 89 | | 98 | | 91 | +--------------+ 3 rows in set (0.00 sec)
