Creating a procedure in mySql with parameters
I am trying to make a stored开发者_StackOverflow社区 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');
