How to insert into two tables using a single MySQL query?
You can use stored procedure to insert into two tables in a single query. Let us first create a table −
mysql> create table DemoTable ( StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, StudentFirstName varchar(20) ); Query OK, 0 rows affected (0.56 sec)
Here is the query to create second table −
mysql> create table DemoTable2 ( ClientId int NOT NULL AUTO_INCREMENT PRIMARY KEY, ClientName varchar(20), ClientAge int ); Query OK, 0 rows affected (0.76 sec)
Following is the query to create stored procedure to insert into two tables created above −
mysql> DELIMITER // mysql> CREATE PROCEDURE insert_into_twoTables(name varchar(100),age int) BEGIN INSERT INTO DemoTable(StudentFirstName) VALUES(name); INSERT INTO DemoTable2(ClientName,ClientAge) VALUES(name,age); END // Query OK, 0 rows affected (0.14 sec) mysql> DELIMITER ;
Now call the stored procedure with the help of CALL command −
mysql> call insert_into_twoTables('Tom',38);
Query OK, 1 row affected, 1 warning (0.41 sec)Check the record is inserted into both tables or not.
The query to display all records from the first table is as follows −
mysql> select * from DemoTable;
This will produce the following output −
+-----------+------------------+ | StudentId | StudentFirstName | +-----------+------------------+ | 1 | Tom | +-----------+------------------+ 1 row in set (0.00 sec)
Following is the query to display all records from the second table −
mysql> select * from DemoTable2;
This will produce the following output −
+----------+------------+-----------+ | ClientId | ClientName | ClientAge | +----------+------------+-----------+ | 1 | Tom | 38 | +----------+------------+-----------+ 1 row in set (0.00 sec)
