我的问题是，如何进一步增强我的查询以区分相同的记录？

Answer 1

您可以选择截止日期，并在选择列表中按其他项目添加分组：

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
order by MOVIE_MASTER.displayorder, max(MOVIE_VERSION.ReleaseDate) desc, distributororder, MOVIE_MASTER.TITLE
