Implement DELETE query in MySQL stored procedure
You can use stored procedure and can pass the value via parameter. Let us first create a table −
mysql> create table DemoTable1464 -> ( -> Id int, -> FirstName varchar(20) -> ); Query OK, 0 rows affected (0.51 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1464 values(101,'Chris Brown'); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable1464 values(102,'John Doe'); Query OK, 1 row affected (0.09 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1464;
This will produce the following output −
+------+-------------+ | Id | FirstName | +------+-------------+ | 101 | Chris Brown | | 102 | John Doe | +------+-------------+ 2 rows in set (0.00 sec)
Here is the query to implement delete query in stored procedure −
mysql> DELIMITER // mysql> CREATE PROCEDURE delete_demo(IN local_Id int, IN local_Name varchar(20)) -> BEGIN -> delete from DemoTable1464 -> where Id=local_Id and -> FirstName=local_Name; -> END // Query OK, 0 rows affected (0.24 sec) mysql> DELIMITER ;
Now you can call the stored procedure using CALL command −
mysql> call delete_demo(102,'John Doe'); Query OK, 1 row affected, 1 warning (0.11 sec)
Let us check the table records once again −
mysql> select * from DemoTable1464;
This will produce the following output −
+------+-------------+ | Id | FirstName | +------+-------------+ | 101 | Chris Brown | +------+-------------+ 1 row in set (0.00 sec)
