Question

我正在努力将mysql查询转换为sql查询，但由于我收到错误，我对sql server没有太多了解，这里我已经发布了我的两个查询，有谁可以帮我解决这个问题查询，我收到错误

Each GROUP BY expression must contain at least one column that is not an outer reference.

Mysql Query（在mysql服务器中正常工作）：

SELECT 'Ending Episodes' as display_name, MonthEnd as MonthStart, MonthEnd as MonthEnd, AVG(FullHHRG) as FullHHRG, 
AVG(LUPAAdj) as LUPAAdj, AVG(OutlierAdd) as OutlierAdd, AVG(UpDownCode) as UpDownCode, AVG(Sequester) as Sequester, 
AVG(NetHHRG) as NetHHRG, count(tb_Episode.id) as total 
FROM tb_Episode 
WHERE EpEnd is not null AND EpEnd >= '01-01-01' AND EpEnd < '01-01-01' AND tb_Episode.CustID = '27' 
GROUP BY display_name, MonthEnd ORDER BY tb_Episode.MonthEnd asc

转换的SQL查询（获取错误）

SELECT 'EndingEpisodes' as display_name, MonthEnd as MonthStart, MonthEnd as MonthEnd, AVG(FullHHRG) as FullHHRG, 
AVG(LUPAAdj) as LUPAAdj, AVG(OutlierAdd) as OutlierAdd, AVG(UpDownCode) as UpDownCode, AVG(Sequester) as Sequester, 
AVG(NetHHRG) as NetHHRG, count(DISTINCT tb_Episode.id) as total 
FROM tb_Episode 
WHERE EpEnd is not null AND EpEnd >= '01-01-01' AND EpEnd < '01-01-01' AND CustID = '27' 
GROUP BY MonthEnd,FullHHRG,LUPAAdj,OutlierAdd,UpDownCode,Sequester,NetHHRG 
ORDER BY MonthEnd asc

Answer 1

我认为您只需要monthend中的group by：

SELECT 'EndingEpisodes' as display_name, MonthEnd as MonthStart, MonthEnd as MonthEnd,
       AVG(FullHHRG) as FullHHRG, AVG(LUPAAdj) as LUPAAdj, AVG(OutlierAdd) as OutlierAdd,
       AVG(UpDownCode) as UpDownCode, AVG(Sequester) as Sequester, 
       AVG(NetHHRG) as NetHHRG, count(DISTINCT tb_Episode.id) as total 
FROM tb_Episode 
WHERE EpEnd is not null AND
      EpEnd >= '01-01-01' AND
      EpEnd < '01-01-01' AND
     CustID = '27' 
GROUP BY MonthEnd
ORDER BY MonthEnd asc;

SQL Server无法识别GROUP BY子句中的列别名，因此问题是无法识别display_name。这是一个常数，所以它没有什么区别。

另请注意，此版本将在MySQL中运行。您可能需要注意日期格式。

Answer 2

我认为您的问题出在group by

上

SELECT 
    'EndingEpisodes' as display_name, 
    MonthEnd as MonthStart, 
    MonthEnd as MonthEnd, 
    AVG(FullHHRG) as FullHHRG, 
    AVG(LUPAAdj) as LUPAAdj, 
    AVG(OutlierAdd) as OutlierAdd, 
    AVG(UpDownCode) as UpDownCode, 
    AVG(Sequester) as Sequester, 
    AVG(NetHHRG) as NetHHRG, 
    count(DISTINCT tb_Episode.id) as total 
FROM tb_Episode 
WHERE EpEnd is not null AND EpEnd >= '01-01-01' AND EpEnd < '01-01-01' AND tb_Episode.CustID = '27' 
GROUP BY MonthEnd
ORDER BY MonthEnd asc
