sqlserver 如何使用count在一条数据中查询呢

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
