Creating a procedure in mySql with parameters

问题

I am trying to make a stored procedure using mySQL. This procedure will validate a username and a password. I'm currently running mySQL 5.0.32 so it should be possible to create procedures.

Heres the code I've used. All I get is an SQL syntax error.

   GO
    CREATE PROCEDURE checkUser
    (IN @brugernavn varchar(64)),IN @password varchar(64))
    BEGIN
    SELECT COUNT(*)  FROM bruger WHERE bruger.brugernavn=@brugernavn AND bruger.pass=@Password;
    END;

Thank you in advance

I figured it out now. Here's the correct answer

CREATE PROCEDURE checkUser 
(
   brugernavn1 varchar(64),
   password varchar(64)
) 
BEGIN 
   SELECT COUNT(*) FROM bruger 
   WHERE bruger.brugernavn=brugernavn1 
   AND bruger.pass=password; 
END;

@ points to a global var in mysql. The above syntax is correct.

(IN @brugernavn varchar(64)**)**,IN @password varchar(64))

The problem is the )

Its very easy to create procedure in Mysql. Here, in my example I am going to create a procedure which is responsible to fetch all data from student table according to supplied name.

DELIMITER //
CREATE PROCEDURE getStudentInfo(IN s_name VARCHAR(64))
BEGIN
SELECT * FROM student_database.student s where s.sname = s_name;
END//
DELIMITER;

In the above example ,database and table names are student_database and student respectively. Note: Instead of s_name, you can also pass @s_name as global variable.

How to call procedure? Well! its very easy, simply you can call procedure by hitting this command

$mysql> CAll getStudentInfo('pass_required_name');
