Let us first create a table −
mysql> create table DemoTable1971 ( StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, StudentName varchar(20), StudentPassword int ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1971(StudentName,StudentPassword) values('John','123456');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1971(StudentName,StudentPassword) values('Chris','123456');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1971(StudentName,StudentPassword) values('David','123456');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1971(StudentName,StudentPassword) values('Mike','123456');
Query OK, 1 row affected (0.00 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1971;
This will produce the following output −
+-----------+-------------+-----------------+ | StudentId | StudentName | StudentPassword | +-----------+-------------+-----------------+ | 1 | John | 123456 | | 2 | Chris | 123456 | | 3 | David | 123456 | | 4 | Mike | 123456 | +-----------+-------------+-----------------+ 4 rows in set (0.00 sec)
Here is the query to create a stored procedure −
mysql> delimiter // mysql> create procedure returnAll(pass varchar(30)) begin select * from DemoTable1971 where StudentPassword=pass; end // Query OK, 0 rows affected (0.00 sec) mysql> delimiter ;
Now you can call a stored procedure using CALL command −
mysql> call returnAll('123456');This will produce the following output displaying the entire table −
+-----------+-------------+-----------------+ | StudentId | StudentName | StudentPassword | +-----------+-------------+-----------------+ | 1 | John | 123456 | | 2 | Chris | 123456 | | 3 | David | 123456 | | 4 | Mike | 123456 | +-----------+-------------+-----------------+ 4 rows in set (0.00 sec) Query OK, 0 rows affected, 1 warning (0.00 sec)
