Question

我有这个SQL查询，通过rand选择限制和顺序，所以我得到每个status的设置数，然后混合整个结果，得到一个随机结果而不是每个status的一个块，并按预期工作：

(SELECT * FROM `vicidial_list` WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "AR" LIMIT 1038)
UNION
(SELECT * FROM `vicidial_list` WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "CBHOLD" LIMIT 372)
UNION
(SELECT * FROM `vicidial_list` WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "NEW" LIMIT 3824)
UNION
(SELECT * FROM `vicidial_list` WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "PI" LIMIT 1405)
UNION
(SELECT * FROM `vicidial_list` WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "NRP" LIMIT 500)
UNION
(SELECT * FROM `vicidial_list` WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "RCAT" LIMIT 500)
ORDER BY RAND()

现在我希望它将list_id更新为200，但这不起作用：

(UPDATE `vicidial_list` SET list_id = 200 WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "AR" LIMIT 1038)
UNION
(UPDATE `vicidial_list` SET list_id = 200 WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "CBHOLD" LIMIT 372)
UNION
(UPDATE `vicidial_list` SET list_id = 200 WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "NEW" LIMIT 3824)
UNION
(UPDATE `vicidial_list` SET list_id = 200 WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "PI" LIMIT 1405)
UNION
(UPDATE `vicidial_list` SET list_id = 200 WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "NRP" LIMIT 500)
UNION
(UPDATE `vicidial_list` SET list_id = 200 WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "RCAT" LIMIT 500)
ORDER BY RAND()

有什么建议吗？

感谢。

只需将每个UPDATE作为单独的声明运行：

UPDATE `vicidial_list` SET list_id = 200 WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "AR" ORDER BY RAND() LIMIT 1038;
UPDATE `vicidial_list` SET list_id = 200 WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "CBHOLD" ORDER BY RAND() LIMIT 372;
UPDATE `vicidial_list` SET list_id = 200 WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "NEW" ORDER BY RAND() LIMIT 3824;
UPDATE `vicidial_list` SET list_id = 200 WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "PI" ORDER BY RAND() LIMIT 1405;
UPDATE `vicidial_list` SET list_id = 200 WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "NRP" ORDER BY RAND() LIMIT 500;
UPDATE `vicidial_list` SET list_id = 200 WHERE phone_number LIKE "7%" AND list_id NOT IN (500,1000) AND status = "RCAT" ORDER BY RAND() LIMIT 500;
