sql语句写法

Question

下面这三个sql语句怎么合并成一个啊? 在一张表里面显示， 这三个sql语句的条件不同select count(*)  搜索任务 from hy_Info  where  hy_info_menuid in(7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23)   group by sys_auserid
 
select count(*) 网盟任务 from hy_Info  where  hy_info_menuid in(24,25,26,27,33,34,35,36,37,38,39,40,41)  group by sys_auserid
 
select count(*) 流程任务 from hy_Info  where  hy_info_menuid in(43,45,47,48,49,50,51,52,54,55,56,57,92,96,123)  group by sys_auserid

Answer 1

select sys_auserid,
       sum(case when hy_info_menuid in(7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23) then 1 else 0 end) [搜索任务],
       sum(case when hy_info_menuid in(24,25,26,27,33,34,35,36,37,38,39,40,41) then 1 else 0 end) [网盟任务],
       sum(case when hy_info_menuid in(43,45,47,48,49,50,51,52,54,55,56,57,92,96,123) then 1 else 0 end) [流程任务]
from hy_Info group by sys_auserid

Answer 2

貌似你的语句有的问题,也影响到我了.
更改为如下:
select sum(case when hy_info_menuid in(7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23) then 1 else 0 end) [搜索任务],
       sum(case when hy_info_menuid in(24,25,26,27,33,34,35,36,37,38,39,40,41) then 1 else 0 end) [网盟任务],
       sum(case when hy_info_menuid in(43,45,47,48,49,50,51,52,54,55,56,57,92,96,123) then 1 else 0 end) [流程任务]
from hy_Info 

Answer 3

select a.[搜索任务],b.[网盟任务],c.[流程任务] from  
(select row_number() over(order by hy_info_menuid) rn,count(*) 搜索任务 from hy_Info where hy_info_menuid in(7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23) group by sys_auserid)a
inner join 
(select row_number() over(order by hy_info_menuid) rn,count(*) 网盟任务 from hy_Info where hy_info_menuid in(24,25,26,27,33,34,35,36,37,38,39,40,41) group by sys_auserid)b on a.rn =b.rn 
inner join 
(select row_number() over(order by hy_info_menuid) rn,count(*) 流程任务 from hy_Info where hy_info_menuid in(43,45,47,48,49,50,51,52,54,55,56,57,92,96,123) group by sys_auserid)c on a.rn =c.rn

Answer 4

select count(*) 搜索任务 from hy_Info where hy_info_menuid in(7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23) group by sys_auserid
union 
select count(*) 网盟任务 from hy_Info where hy_info_menuid in(24,25,26,27,33,34,35,36,37,38,39,40,41) group by sys_auserid
union  
select count(*) 流程任务 from hy_Info where hy_info_menuid in(43,45,47,48,49,50,51,52,54,55,56,57,92,96,123) group by sys_auserid
