Copy a few columns from a table to another in MySQL
Let us first create a table −
mysql> create table DemoTable1 -> ( -> Id int, -> Name varchar(100) -> ); Query OK, 0 rows affected (0.53 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1 values(10,'John'); Query OK, 1 row affected (0.23 sec) mysql> insert into DemoTable1 values(11,'Chris'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable1 values(12,'Robert'); Query OK, 1 row affected (0.32 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
This will produce the following output −
+------+--------+ | Id | Name | +------+--------+ | 10 | John | | 11 | Chris | | 12 | Robert | +------+--------+ 3 rows in set (0.00 sec)
Following is the query to copy few columns from a DemoTable1 to another table DemoTable2 −
mysql> create table DemoTable2 ( -> select Name from DemoTable1 where Id=11 -> ); Query OK, 1 row affected (0.70 sec) Records: 1 Duplicates: 0 Warnings: 0
Now check the table records of table ‘DemoTable2’ −
mysql> select *from DemoTable2;
Output
This will produce the following output −
+-------+ | Name | +-------+ | Chris | +-------+ 1 row in set (0.00 sec)
