调用存储过程

Question

DROP PROCEDURE IF EXISTS checkExistingEmail;
delimiter $$

CREATE PROCEDURE checkExistingEmail(
 IN parmEmail VARCHAR(100)
,IN parmFName VARCHAR(100)
,IN parmLName VARCHAR(100)
,IN parmPassword VARCHAR(60)
,OUT RetVal TINYINT
,OUT UID VARCHAR(36)
) 
BEGIN


	IF EXISTS (SELECT email FROM User_Registration WHERE email = parmEmail) THEN
    	SET RetVal = 0; 
        SET UID = null;
    ELSE
		
        SET UID = UUID();
        SET RetVal = 1; 
        
        INSERT INTO User_Registration(Email,FirstName,LastName,Password,GUID)
        VALUES(parmEmail,parmFName,parmLName,parmPassword,UID);
	END IF;
END

我收到了SQL语法错误，但我无法弄清问题是什么。问题只发生在我将应用程序推送到OpenShift时。它在我的快速应用程序和MySQL Workbench中都可以在本地运行。

它没有任何意义，因为我可以在PHP管理控制台中执行此语句。

我正在使用MySQL 5.5。

Error: { [Error: ER_PARSE_ERROR: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT @RetVal as retVal,@UID as uid' at line 1]

这表明它在本地工作。
