两个查询sql如何合并在一起呢
select
'区域' as Area,
'名称' as MineName,
count(1) as '在线'
from sys_PointInfo
where sysCode=121 and Value =0
group by Area,MineName
select
'区域' as Area,
'名称' as MineName,
count(1) as '不在线'
from sys_PointInfo
where sysCode=121 and (Value !=0 or value is null)
group by Area,MineName
select
'区域' as Area,
'名称' as MineName,
count(case when Value =0 then 1 end) as '在线',
count(case when (Value !=0 or value is null) then 1 end) as '不在线'
from sys_PointInfo
where sysCode=121
group by Area,MineName
把这两个子查询连接查询,不会的话,把你的表结构和数据sql发出来看看,还有,你这个查询语句在查什么东西,完全没看懂
