SELECT DISTINCT不同於結果

下面是查詢SELECT DISTINCT不同於結果

select DISTINCT movie_master.MovieMasterID, MOVIE_VERSION.ReleaseDate, 
movie_master.displayorder,movie_classification.mc_code, 
movie_master.title As Title, 
movie_master.BioCast,movie_master.BioDirector,movie_master.LinkWord, 
CASE WHEN ((DATEDIFF(day,MOVIE_VERSION.ReleaseDate,getdate()) <=7) and (DATEDIFF(day,MOVIE_VERSION.ReleaseDate,getdate()) >=0)) THEN 'JUST RELEASED' ELSE '' END AS RELEASETAG, 
movie_master.Synopsis,movie_language.NAME as Language, 
CASE WHEN movie_master.DistributorID = 8 THEN 0 ELSE 9999 END AS distributororder, 
movie_distributor.name as distributor 
from movie_master 
left join MOVIE_LANGUAGE on MOVIE_MASTER.Language = movie_language.languageid 
left join movie_distributor on MOVIE_MASTER.distributorid = movie_distributor.distributorid 
left join movie_version on MOVIE_MASTER.MovieMasterID = MOVIE_VERSION.MovieMasterID 
left join movie_classification on MOVIE_MASTER.classification = movie_classification.classificationid 
left join movie_itemdetails on MOVIE_MASTER.MovieMasterID = movie_itemdetails.MovieMasterID 
where MOVIE_VERSION.ReleaseDate <= convert(varchar, GETDATE(), 101) 
and MOVIE_VERSION.MovieMasterID = movie_master.MovieMasterID 
and movie_master.classification = movie_classification.classificationid 
and movie_master.MovieMasterID = movie_itemdetails.MovieMasterID and movie_itemdetails.fieldid = 1 and movie_itemdetails.Type ='TRAILER' 
and ((MOVIE_VERSION.FilmCode in (SELECT DISTINCT FILMID FROM MOVIE_TEMP)) OR (MOVIE_VERSION.Title in (SELECT DISTINCT TITLE FROM MOVIE_TEMP))) 
AND LEFT(MOVIE_VERSION.FILMCODE,1) <> 6 
and MOVIE_VERSION.Enabled = 1 
AND MOVIE_MASTER.Enabled = 1 
AND (MOVIE_MASTER.MovieMasterID in (SELECT DISTINCT MOVIE_MASTER.MovieMasterID FROM MOVIE_MASTER)) 
order by MOVIE_MASTER.displayorder, MOVIE_VERSION.ReleaseDate desc, distributororder, MOVIE_MASTER.TITLE

和結果集

我的問題是，我怎麼能進一步提高我的查詢到不同相同的記錄？

我在結果集中看不到任何重複記錄 – 2013-03-05 10:04:58

沒有重複的記錄。具有相同名稱的記錄具有不同的日期，即有兩個版本具有不同的發佈日期。 – Guffa 2013-03-05 10:05:15

對不起，我不是想說重複的記錄。是的，具有相同名稱和不同日期的記錄，我如何進一步區分它們以顯示1條記錄而不是2條記錄？ – user2135208 2013-03-05 10:09:31

您可以選擇最後日期，以及在選擇列表中的其他項目添加分組：

select DISTINCT movie_master.MovieMasterID, max(MOVIE_VERSION.ReleaseDate), 
movie_master.displayorder, movie_classification.mc_code, 
movie_master.title As Title, 
movie_master.BioCast, movie_master.BioDirector, movie_master.LinkWord, 
CASE WHEN ((DATEDIFF(day,max(MOVIE_VERSION.ReleaseDate),getdate()) <=7) 
and (DATEDIFF(day,max(MOVIE_VERSION.ReleaseDate),getdate()) >=0)) 
THEN 'JUST RELEASED' ELSE '' END AS RELEASETAG, 
movie_master.Synopsis,movie_language.NAME as Language, 
CASE WHEN movie_master.DistributorID = 8 THEN 0 ELSE 9999 END AS distributororder, 
movie_distributor.name as distributor 
... 
group by movie_master.MovieMasterID, movie_master.displayorder, movie_classification.mc_code, 
movie_master.title, movie_master.BioCast, movie_master.BioDirector, 
movie_master.LinkWord, movie_master.Synopsis, 
movie_language.NAME, movie_master.DistributorID, movie_distributor.name

您好Polina，您的查詢並沒有真正解決我正在尋找的輸出。我仍然有相同的記錄，並希望保留您刪除的「Order By」 – user2135208 2013-03-05 10:20:58

您應該在「按...排序」之前添加「group by ...」 – Polina 2013-03-05 10:27:56

Hi Polina，它仍然給相同的結果 – user2135208 2013-03-05 10:34:24

謝謝，但錯誤被捕獲 - 列'MOVIE_VERSION.ReleaseDate'在HAVING子句中無效，因爲它不包含在集合函數或GROUP BY子句中。 – user2135208 2013-03-05 10:45:21
