[mysql] how to write procedure to insert data in to the table in phpmyadmin?

I have created table as below:

student:
+----+------+-----------+--------+
|uid | name | user_name | branch |
+----+------+-----------+--------+
|    |      |           |        |
+----+------+-----------+--------+

I want to insert data in to the table using procedure.

the procedure which i wrote is:

create procedure add(in_name varchar(50),in_user_name varchar(50),in_branch varchar(50))
begin
insert into student (name,user_name,branch) values (in_name ,in_user_name,in_branch);
end;

# Switch delimiter to //, so phpMyAdmin will not execute it line by line.
DELIMITER //
CREATE PROCEDURE usp_rateChapter12

(IN numRating_Chapter INT(11) UNSIGNED, 

 IN txtRating_Chapter VARCHAR(250),

 IN chapterName VARCHAR(250),

 IN addedBy VARCHAR(250)

)

BEGIN
DECLARE numRating_Chapter INT;

DECLARE txtRating_Chapter VARCHAR(250);

DECLARE chapterName1 VARCHAR(250);

DECLARE addedBy1 VARCHAR(250);

DECLARE chapterId INT;

DECLARE studentId INT;

SET chapterName1 = chapterName;
SET addedBy1 = addedBy;

SET chapterId = (SELECT chapterId 
                   FROM chapters 
                   WHERE chaptername = chapterName1);

SET studentId = (SELECT Id 
                   FROM students 
                   WHERE email = addedBy1);

SELECT chapterId;
SELECT studentId;

INSERT INTO ratechapter (rateBy, rateText, rateLevel, chapterRated)
VALUES (studentId, txtRating_Chapter, numRating_Chapter,chapterId);

END //

//DELIMITER;

This method work for me:

DELIMITER $$
DROP PROCEDURE IF EXISTS db.test $$
CREATE PROCEDURE db.test(IN id INT(12),IN NAME VARCHAR(255))
 BEGIN
 INSERT INTO USER VALUES(id,NAME);
 END$$
DELIMITER ;
