Perform mathematical operations in a MySQL Stored Procedure?
Let us create a stored procedure. Here, we are calculating amount*quantity i.e. implementing mathematical operations −
mysql> delimiter // mysql> create procedure calculation_proc(amount int,quantity int) begin select amount,quantity,(amount*quantity) as Total; end // Query OK, 0 rows affected (0.00 sec) mysql> delimiter ;
Now you can call a stored procedure using call command −
mysql> call calculation_proc(250,3);
This will produce the following output −
+--------+----------+-------+ | amount | quantity | Total | +--------+----------+-------+ | 250 | 3 | 750 | +--------+----------+-------+ 1 row in set (0.00 sec) Query OK, 0 rows affected (0.00 sec)
