sql添加合计

在项目中发现有这样的写法

SELECT ZoneID,CountSQAZFZSBJZ3G+CountSQGZJRJZSL3G AS column1
FROM G3MulticarrierSiteCoverTableFrm

union

SELECT 合计 as ZoneID,sum(CountSQAZFZSBJZ3G+CountSQGZJRJZSL3G) AS column1
FROM G3MulticarrierSiteCoverTableFrm

发面“CountSQAZFZSBJZ3G+CountSQGZJRJZSL3G”有很多这样的业务，都是复制一次，容易漏掉，导致数据不对。

可以改成

在这里写一次“CountSQAZFZSBJZ3G+CountSQGZJRJZSL3G”就行了。

select isnull(CONVERT(varchar(20), ZoneID),‘Total‘) as ‘emp_id‘
,sum(t.column1) as ‘qty_Total‘
from (SELECT ZoneID,CountSQAZFZSBJZ3G+CountSQGZJRJZSL3G AS column1
FROM G3MulticarrierSiteCoverTableFrm) t
group by ZoneID
with rollup
