在这里,我试图通过使用我已经创建的功能来计算在病房中部署的护士数量,从输入的病房ID中计算病房护士的数量
select @NoNursesDpd = dbo.fnc1(@InputtedWardID),
@wardID, @WardName
select WardID, WardName
from WardTbl
where @InputtedWardID = WardID and @WardName = WardName
end
我收到错误
为变量赋值的SELECT语句不能与数据检索操作结合使用。
有谁知道如何将它包装成一个select语句?

如果您不需要变量进行进一步处理,只需将其包含在结果集中:
select
dbo.fnc1(@InputtedWardID) AS NoNursesDpd ,
WardID,
WardName
from WardTbl
where @InputtedWardID = WardID and @WardName = WardName

而不是
select @NoNursesDpd = dbo.fnc1(@InputtedWardID),
@wardID, @WardName
select WardID, WardName
from WardTbl
where @InputtedWardID = WardID and @WardName = WardName
end
试试这个:
select WardID, WardName, dbo.fnc1(WardID)
from WardTbl
where WardID = @InputtedWardID
end
