如何一次运行多个mysql查询

Question

我在MySQL中有两个查询

select count(activity_id) from asd where ico_detail_id = '5a673c68a895200d64cd6a18' and activity_id = 1 and is_active = 1;

select count(activity_id) from asd where ico_detail_id = '5a673c68a895200d64cd6a18' and activity_id = 2 and is_active = 1;

我想使用该过程或其他方法一次运行这两个查询。

需要帮助。 Thanxx in adv

Answer 1

使用条件聚合，

SELECT  SUM(CASE WHEN activity_id = 1 THEN 1 ELSE 0 END) activity_id_1,
        SUM(CASE WHEN activity_id = 2 THEN 1 ELSE 0 END) activity_id_2
FROM    bulltoken.ico_vote 
WHERE   ico_detail_id = '5a673c68a895200d64cd6a18' 
        AND is_active = 1;

这将显示：

---------------+---------------
activity_id_1  +  activity_id_2
---------------+---------------
10             +  20          
---------------+---------------

Answer 2

select count(activity_id) from bulltoken.ico_vote where ico_detail_id = '5a673c68a895200d64cd6a18' and activity_id = 1 and is_active = 1;
UNION
select count(activity_id) from bulltoken.ico_vote where ico_detail_id = '5a673c68a895200d64cd6a18' and activity_id = 2 and is_active = 1;
