For this, use INSERT INTO SELECT statement in MySQL. Let us create a table −
mysql> create table demo61 −> ( −> id int, −> name varchar(20) −> ) −> ; Query OK, 0 rows affected (1.84 sec)
Insert some records into the table with the help of insert command −
mysql> insert into demo61 values(1,'John'); Query OK, 1 row affected (0.63 sec) mysql> insert into demo61 values(2,'David'); Query OK, 1 row affected (0.13 sec) mysql> insert into demo61 values(1,'Mike'); Query OK, 1 row affected (0.10 sec) mysql> insert into demo61 values(2,'Carol'); Query OK, 1 row affected (0.30 sec) mysql> insert into demo61 values(2,'Bob'); Query OK, 1 row affected (0.09 sec)
Display records from the table using select statement −
mysql> select *from demo61;
This will produce the following output −
+------+-------+ | id | name | +------+-------+ | 1 | John | | 2 | David | | 1 | Mike | | 2 | Carol | | 2 | Bob | +------+-------+ 5 rows in set (0.00 sec)
Following is the query to create second table.
mysql> create table demo62 -> ( −> employee_id int not null auto_increment primary key, −> employee_name varchar(20) −> ); Query OK, 0 rows affected (1.60 sec)
Insert some records into the table with the help of insert command −
mysql> insert into demo62(employee_name) −> select name from demo61 where id=2; Query OK, 3 rows affected (0.14 sec) Records: 3 Duplicates: 0 Warnings: 0
Display records from the table using select statement −
mysql> select *from demo62;
This will produce the following output −
+-------------+---------------+ | employee_id | employee_name | +-------------+---------------+ | 1 | David | | 2 | Carol | | 3 | Bob | +-------------+---------------+ 3 rows in set (0.00 sec)
