問題描述

我使用的是 Microsoft SQL Svr Mgmt Studio 2008.我無權創(chuàng)建臨時表(公司限制創(chuàng)建或修改表的能力)，或者我會用它來解決這個問題.

I'm using Microsoft SQL Svr Mgmt Studio 2008. I don't have access to create a temporary table (company restricts ability to create or modify tables) or I would use that to solve this problem.

我已經(jīng)成功地使用聯(lián)合查詢來組合三個選擇查詢的結果.現(xiàn)在我試圖總結聯(lián)合的結果.

I have successfully used a union query to combine the results of three select queries. Now I am trying to sum the results of the union.

當我執(zhí)行下面的查詢時，我收到:

When I execute the query below I receive:

Incorrect syntax near the keyword 'GROUP'

然后當我通過我刪除組時:

And then when I remove the group by I get:

Incorrect syntax near ')'

這是我目前的查詢:

Select Period, PCC, SUM(BasicHits), SUM(FareHits), SUM(SearchHits)
From (

SELECT     AAAPeriod AS Period, 
AAAFromPCC AS PCC, 
- SUM(AAABasic) AS BasicHits,
- SUM(AAAFare) AS FareHits,
- SUM(AAASearch) AS SearchHits
FROM        HitsAaa
HAVING     (AAAPeriod = N'2010-10') 

UNION ALL

SELECT     AAAPeriod, 
AAAtoPCC,
SUM(AAABasic),
SUM(AAAFare),
SUM(AAASearch) 
FROM        HitsAaa
HAVING     (AAAPeriod = N'2010-10')

UNION ALL

SELECT      AgtPeriod, 
AgtPcc, 
SUM(AgtBasic),
SUM(AgtFare),
SUM(AgtSearch)
FROM          HitsAgent
HAVING      (AgtPeriod = N'2010-10')

)GROUP BY Period, PCC

對于之前的任何問題，我都無法找到解決方案.

I haven't been able to find a solution to this on any of the previous questions.

推薦答案

你需要給你的派生表取別名，你還必須使用一個帶有 have 子句的 group by.

You need to alias your derived table, you must also use a group by with a having clause.

SELECT
  q1.Period, 
  q1.PCC, 
  SUM(q1.BasicHits), 
  SUM(q1.FareHits), 
  SUM(q1.SearchHits)
FROM (SELECT     
        AAAPeriod AS Period, 
        AAAFromPCC AS PCC, 
        - SUM(AAABasic) AS BasicHits,
        - SUM(AAAFare) AS FareHits,
        - SUM(AAASearch) AS SearchHits
      FROM HitsAaa
      GROUP BY 
        AAAPeriod, 
        AAAFromPCC
      HAVING (AAAPeriod = N'2010-10') 

      UNION ALL

      SELECT     
        AAAPeriod AS Period, 
        AAAtoPCC AS PCC,
        SUM(AAABasic) AS BasicHits,
        SUM(AAAFare) AS FareHits,
        SUM(AAASearch) AS SearchHits 
      FROM HitsAaa
      GROUP BY 
        AAAPeriod, 
        AAAtoPCC
      HAVING (AAAPeriod = N'2010-10')

      UNION ALL

      SELECT
        AgtPeriod AS Period, 
        AgtPcc AS PCC, 
        SUM(AgtBasic) AS BasicHits,
        SUM(AgtFare) AS FareHits,
        SUM(AgtSearch)  AS SearchHits
      FROM HitsAgent
      GROUP BY 
        AgtPeriod, 
        AgtPCC
      HAVING (AgtPeriod = N'2010-10')) q1 
GROUP BY 
  q1.Period, 
  q1.PCC
