Select some data from a database table and insert into another table in the same database with MySQL

To insert data from a table to another, use INSERT INTO statement. Let us first create a table −

mysql> create table DemoTable1      (      Id int,      FirstName varchar(20),      Age int      ); Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1 values(101,'Chris',24); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1 values(102,'David',28); Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1;

This will produce the following output −

+------+-----------+------+ | Id   | FirstName | Age  | +------+-----------+------+ |  101 | Chris     |   24 | |  102 | David     |   28 | +------+-----------+------+ 2 rows in set (0.00 sec)

Here is the query to create second table.

pre class="prettyprint notranslate" > mysql> create table DemoTable2      (      EmployeeId int,      EmployeeName varchar(20),      EmployeeAge int      ); Query OK, 0 rows affected (0.00 sec)

Following is the query to select some data from one database table and insert into another table in the same database −

mysql> insert into DemoTable2(EmployeeId,EmployeeName,EmployeeAge)      select Id,FirstName,Age from DemoTable1 where Id=102; Query OK, 1 row affected (0.00 sec) Records: 1  Duplicates: 0  Warnings: 0

Display all records from the table using select statement −

mysql> select * from DemoTable2;

This will produce the following output −

+------------+--------------+-------------+ | EmployeeId | EmployeeName | EmployeeAge | +------------+--------------+-------------+ |        102 | David        |          28 | +------------+--------------+-------------+ 1 row in set (0.00 sec)
