为什么我的PHP不会返回MySQL存储过程？

Question

嗯，我认为我写的，如果我运行phpMyAdmin的东西下面的正确返回这个MySQL存储过程：提供的参数无效：

SELECT game_name,urlfriendly(game_name) AS game_name2 FROM games 

但是，如果我尝试运行下面的代码我得到的错误“警告为的foreach（）在/filepath.php线＃”

foreach ($this->database->query("SELECT game_name,urlfriendly(game_name) AS game_name2 FROM games") as $games) 
{ 
    echo $games["game_name"] . " " . $games["game_name2"]; 
} 

但是，如果我跑这一点，一切顺利的罚款：

foreach ($this->database->query("SELECT game_name FROM games") as $games) 
{ 
    echo $games["game_name"]; 
} 

含义ŧ他存储过程不会返回到PHP。

任何想法？

编辑这里的存储过程（但我怀疑这是问题，因为phpMyAdmin是从它就好拉后的值）

DELIMITER //

DROP FUNCTION urlfriendly 
// 
CREATE FUNCTION urlfriendly (unsafe TEXT) RETURNS TEXT 

DETERMINISTIC 

BEGIN 

DECLARE safe TEXT; 

SET safe = REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(LOWER(unsafe),' ','-'),'&','and'),'`',''),'~',''),'!',''),'@',''),'#',''),'$',''),'%',''),'^',''),'*',''),'(',''),')',''),'_',''),'+',''),'=',''),'[',''),'{',''),']',''),'}',''),'|',''),'\\',''),"'",""),'"',''),':',''),';',''),'<',''),',',''),'>',''),'.',''),'/',''),'?',''); 

RETURN safe; 

END 
// 

EDIT2这里是从MySQL返回的错误

execute command denied to user 'username'@'localhost' for routine 'databasename.urlfriendly') 

Answer 1

你能得到errorInfo？

你可以运行：

GRANT EXECUTE ON `database`.* TO 'username'@'localhost' 

从phpMyAdmin的？
