您没有超级权限,二进制日志记录已启用(您 可以 希望使用不太安全的log\u bin\u trust\u function\u creators变量)

CREATE FUNCTION `has_action_access`(in_role VARCHAR(255), in_request VARCHAR(255), in_action VARCHAR(255)) RETURNS tinyint(1)
    READS SQL DATA
    DETERMINISTIC
BEGIN

    DECLARE current_role VARCHAR(255);  
    DECLARE found, cont TINYINT(1) DEFAULT 0;
    SET current_role = in_role;

    findattempt: REPEAT
        SELECT COUNT(*) FROM cyp_action_access WHERE request = in_request AND action = in_action AND role = current_role INTO found;

        IF found = 0 THEN
            SELECT COUNT(*) FROM cyp_roles WHERE name = current_role INTO cont;
            IF cont = 1 THEN
                SELECT inherits FROM cyp_roles WHERE name = current_role INTO current_role;
                END IF;
            END IF;
    UNTIL (cont = 0 OR found > 0) END REPEAT;
    RETURN found;
END;
