MySQL的过程不是excecuting

这是我的程序MySQL的过程不是excecuting

DELIMITER // 
    CREATE PROCEDURE GET_CHECK_COURSES(IN distid int, IN `accescodeString` TEXT) 
    BEGIN 


CREATE TEMPORARY TABLE IF NOT EXISTS accesstmp (
`Id` INT NOT NULL AUTO_INCREMENT, 
`accesscode` VARCHAR(100) NOT NULL, 
PRIMARY KEY (`Id`)) ENGINE=InnoDB; 

@query = "INSERT INTO accesstmp (`accesscode`) VALUES ('",accescodeString,"')"; 

    PREPARE stmt1 FROM @query; 
    EXECUTE stmt1; 
    DEALLOCATE PREPARE stmt1; 

    @query1 = "SELECT 
    cde.code_status, 
    co.course_code, 
    co.course_name, 
    u.organization, 
    u1.email as licencinguser, 
    cul.status, 
    cul.learning_completion_date 
    FROM cdp_access_codes as cde 
    LEFT JOIN cdp_course as co ON cde.course_id = co.course_id 
    LEFT JOIN cdp_user as u ON u.user_id = cde.licensing_user_id 
    LEFT JOIN cdp_user as u1 ON u1.user_id = cde.user_id 
    LEFT JOIN cdp_accesscode_courses as cac ON cac.code_id = cde.code_id 
    LEFT JOIN cdp_user_licenses as cul ON cul.user_license_id = cac.course_subscription_id 
    JOIN accesstmp as act ON act.accesscode = cde.access_code 
    WHERE 
    cde.distributor_user_id = $distributorId 
    GROUP BY cde.access_code"; 


    PREPARE stmt2 FROM @query1; 
    EXECUTE stmt2; 
    DEALLOCATE PREPARE stmt2; 



    END // 
    DELIMITER ;

但是，当我执行此我得到一个语法错误

#1064 - 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 '@query = "INSERT INTO accesstmp (`accesscode`) VALUES ('",accescodeString,"')"; ' at line 10

我parametrs都是这样的参数值的方式distid = 24和accescodeString是严格“mmmm，ssss，eeee”

请任何人帮助我。在此先感谢。

我不认为有必要使用13.5准备的SQL语句语法]（https://dev.mysql.com/ doc/refman/5.7/en/sql-syntax-prepared-statements.html）在'INSERT'中。 '$ distributorId'变量应该是一个输入参数。使用[13.7.4 SET语法]（https://dev.mysql.com/doc/refman/5.7/en/set-statement.html）分配[9.4用户定义的变量]（https：// dev。 mysql.com/doc/refman/5.7/en/user-variables.html）（'\'@query \''）。使用['CONCAT（）']（https://dev.mysql.com/doc/refman/5.7/en/string-functions.html#function_concat）函数进行连接。 – wchiquito

必须使用concat和set局部变量，例如@variable：

set @query = concat("INSERT INTO accesstmp (`accesscode`) VALUES ('",accescodeString,"')"); 


-- ... 

set @query1 = "SELECT ...
