使用按查询分组查找部门计数

Question

我需要查找部门中存在的建筑物数量，因此我使用下面的查询

  select sil.Name, Count((select * from Common.Building where TypeCode=10012)), Count((select * from Common.Building where TypeCode=98)) from Common.Building ok
  join Skrs.Department sil on ok.DepartmentId=sil.Id
  group by sil.Name

这是sql错误消息：

  

＆＃34;无法对包含的表达式执行聚合函数   聚合或子查询＆＃34;

如何检索数据？

已编辑：样本数据：

Answer 1

我猜你想要这样的东西：

select sil.Name,
       sum(case when b.TypeCode = 10012 then 1 else 0 end),
       sum(case when b.TypeCode = 98 then 1 else 0 end)
from Common.Building b join
     Skrs.Department sil
     on b.DepartmentId = sil.Id
group by sil.Name;
