MySQL Update Query Successfull But Values Doesn't Changing At All - mysql

Question

I have a problem, I created a stored procedure to activate users by sending their email id and activation key
this is the SQL syntax (in MySQL)
DELIMITER $$
CREATE PROCEDURE `dbname`.`sp_userActivate` (
IN email VARCHAR(140),
IN ac VARCHAR(64)
)
BEGIN
SET SQL_SAFE_UPDATES=0;
UPDATE user SET activated = 1
WHERE user.email = email AND
user.activation_key=ac;
commit;
END
When I execute the syntax, it's successfully executed, but when I take a look in the table, the value activated still remains = 0 (not updated at all)
I have looked more than twice to ensure the email and activation is equal with is stored in table,
What's wrong with this Query?
UPDATE
This is my table structure in schema
Thanks in advance for your help.
SQL Statement for Create table
CREATE TABLE IF NOT EXISTS `db`.`user` (
`no` INT(11) NOT NULL AUTO_INCREMENT ,
`username` VARCHAR(140) NOT NULL ,
`password` VARCHAR(128) NOT NULL ,
`firstname` VARCHAR(300) NOT NULL ,
`lastname` VARCHAR(300) NULL DEFAULT NULL ,
`email` VARCHAR(140) NOT NULL ,
`pepper` CHAR(128) NOT NULL ,
`activation_key` VARCHAR(64) NULL DEFAULT NULL ,
`gender` CHAR(1) NULL DEFAULT NULL ,
`activated` CHAR(1) CHARACTER SET 'latin1' COLLATE 'latin1_bin' NULL DEFAULT '0' ,
PRIMARY KEY (`no`) ,
UNIQUE INDEX `username` (`username` ASC) ,
UNIQUE INDEX `email` (`email` ASC) ,
INDEX `user_firstname_idx` (`firstname` ASC) ,
INDEX `user_lastname_idx` (`lastname` ASC) )
For Example Row
insert into
user(username, password,firstname, lastname, email,pepper,activation_key,gender)
values("usr1test","c781bf44a464a5946ef36a7250f5504388914bbf6287fabaf938472f46c413d71cd7bf2b3077eeac8675419d5f022ff3652ba7e13e8","user1","test","usr1test#localhost","af41bfa3c9324f39fd82f84125967b38969662256cf8249e73e3bd2cef3928b5","OGE4Y2E2OWUtMmM2Mi00MjJkLWI0NTQtNzJkZDQ1OTcxNjUx",'M');

Answer 1

Here is the procedure, that worked for me:
DROP PROCEDURE IF EXISTS sp_userActivate;
DELIMITER $$
CREATE PROCEDURE sp_userActivate (
IN email VARCHAR(140),
IN ac VARCHAR(64)
)
BEGIN
SET SQL_SAFE_UPDATES=0;
UPDATE `user`
SET activated = 1
WHERE
`user`.`email` = email
AND
`user`.`activation_key` = ac;
COMMIT;
END $$
DELIMITER ;
Run this, then try:
CALL sp_userActivate('usr1test#localhost',
'OGE4Y2E2OWUtMmM2Mi00MjJkLWI0NTQtNzJkZDQ1OTcxNjUx');
It worked correctly on my machine.

Answer 2

okay, after see the table data in my table. It seems that the key is have BLANK space after the last character.
example :
-- with blank space:
ZWRhNzZmMzMtMmI2Ny00NDBlLTkxNTUtNmQ2MWIwYjg3MzA4_ (see _ ?)
-- without blank space: ZWRhNzZmMzMtMmI2Ny00NDBlLTkxNTUtNmQ2MWIwYjg3MzA4
so, the MySQL see point no 1 and 2 are different.
I hope this makes my problem clear.
