MySQL如何选择mulipie行，然后发送到另一个查询

我有一张桌子，我可以用

SELECT `event_id` FROM `event` WHERE 1

要获取mulipie行的event\u id，我将event\u id放在这个查询中

SET @event_id = XXXX;
SELECT * FROM(
(SELECT `event_id`,`author_id`,`latitude`,`longitude`,`type`,`rate`,`description`,`photo_id`, UNIX_TIMESTAMP(`timestamp`) AS `timestamp` 
FROM `event`) AS `event`,
(SELECT COUNT(*) AS `thumb_up_count` FROM `thumb_event` WHERE `event_id` = @event_id AND `thumb_state` = 1) AS `thumb_up_count`,
(SELECT COUNT(*) AS `thumb_down_count` FROM `thumb_event` WHERE `event_id` = @event_id AND `thumb_state` = 2) AS `thumb_down_count`,
(SELECT IFNULL((SELECT `thumb_state` FROM `thumb_event` WHERE `event_id` = @event_id AND `user_id` = ?) , 0) AS `thumbed`) AS `thumbed`,
(SELECT COUNT(*) AS `comment_count` FROM `event_comment` WHERE `event_id` = @event_id) AS `comment_count`
) WHERE `event_id` = @event_id;

我可以使用

SET@event\u id=0000

设置

event\u id

，但如何将select中的所有

event\u id

放入该查询中

如果我了解，可能您需要的是in子句：

WHERE `event_id` IN (SELECT `event_id` FROM `event` WHERE 1);
