为什么会发生这种情况？

mysql> DROP PROCEDURE IF EXISTS GetUserByUserID;
Query OK, 0 rows affected


    mysql> DELIMITER $$
    mysql> CREATE PROCEDURE GetUserByUserID(IN userID VARCHAR(32))
        BEGIN
            PREPARE stmt1 FROM 'SELECT u.*, usg.SCHOOL_GRADE_ID FROM PF_USER u LEFT JOIN PF_USER_SCHOOL_GRADE usg ON u.USER_ID=usg.USER_ID AND u.USER_ID=?';
            SET @a = userID;
            EXECUTE stmt1 USING @a;
            DEALLOCATE PREPARE stmt1;
        END $$
    DELIMITER ;

mysql> call GetUserByUserID(000E8893F29ED6E84CECCB0FA8B869D1);

mysql> call GetUserByUserID('000E8893F29ED6E84CECCB0FA8B869D1');
