有谁知道为什么我在下面不断收到此错误？我似乎无法动摇它。

call test_delete('WOW@GMAIL.COM', '''2c016cd6-87e6-11e1-9fac-001cd4565d26''', 0) Error Code: 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 'UPDATE user u SET u.enable = ? WHERE u.' at line 2

    CREATE PROCEDURE `test_delete`(
        IN username NVARCHAR(255),
        IN district_admin_ids LONGTEXT,

    )
    BEGIN

    SET @username = username;
    SET @district_admin_ids = district_admin_ids;
    SET @active = CASE WHEN active > 0 THEN 1 ELSE 0 END;

    SET @query = CONCAT('

移到SET SQL_SAFE_UPDATES=0;动态查询之外并且它起作用了。
