Can we use stored procedure to insert records into two tables at once in MySQL?

Yes, 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)
