Question

我有一张包含所有代理记录的表格。我设置了几个查询，计算这些记录的具体内容，每个查询按日期对它们进行分组。我想弄清楚的是我如何将这些查询组合成一个新的查询。现在，我运行每个，将它们放入Excel，然后执行vlookup并将它们合并为一个。以下是我的两个问题。

查询＃1：

select 
    LocationStateAbr,
    count(LocationStateAbr) as "Total Agencies" 
from
    [PROD_Agency].[dbo].[AgAgency]
where 
    StatusId = ' ' 
    and BusinessId in ('b', 'C') 
    and TypeId in ('A', 'C', 'F', 'I', 'X') 
group by 
    LocationStateAbr
order by 
    LocationStateAbr ASC

查询＃2：

select 
    LocationStateAbr,
    count(LocationStateAbr) as "New Agencies" 
from
    [PROD_Agency].[dbo].[AgAgency]
where 
    year(AppointedDt) = 2018 
    and StatusId = ' ' 
    and BusinessId in ('b', 'C') 
    and TypeId in ('A', 'C', 'F', 'I', 'X') 
group by 
    LocationStateAbr
order by 
    LocationStateAbr ASC

有什么建议吗？谢谢！

您可以使用CASE将两个查询合并为一个。在你的情况下，它将是这样的：

select 
    LocationStateAbr,
    count(case when StatusId = ' ' 
          and BusinessId in ('b', 'C') 
          and TypeId in ('A', 'C', 'F', 'I', 'X') then 1 else null end) as "Total Agencies",
    count(case when year(AppointedDt) = 2018 
          and StatusId = ' ' 
          and BusinessId in ('b', 'C') 
          and TypeId in ('A', 'C', 'F', 'I', 'X') the 1 else null end) as "New Agencies"
FROM
   [PROD_Agency].[dbo].[AgAgency]
group by 
    LocationStateAbr
order by 
    LocationStateAbr ASC
