SQL Server:LIMIT不处理复杂查询

Question

我有一个相当漫长而复杂的SQL查询,我正在研究这个问题.

我想要做的只是添加LIMIT 10...但每次我结束它到查询的结尾我都会收到错误.

任何帮助都会很棒,查询如下:

sqlQuery = "
  select      DATENAME(Month,i.Datecreated) + ' ' + 
              DATENAME(day,i.Datecreated) + ' ' + 
              DATENAME(year,i.Datecreated) AS USDateCreated,
              i.imageId,
              GalleryName,Fullpath,MediumPath,ThumbPath,ViewCounter,
              i.DateCreated,ItemNumber,Gender,Minutes,
              right(convert(varchar(3), 100 + Seconds),2) as Seconds,
              FramesPerSecond,WeekNumber,Filename,
              (round(cast(Size as Decimal(16,2))/1024,2)) as Size,
              FlvFilename,FlvSize,NumberOfMovies,
              Free,Comment,
              (case when sum(rating)/count(i.imageId) is null then 0 else sum(rating)/count(i.imageId) end) as ratingResult, 
              dbo.getTagNames(i.imageid) as tagsname,'' as yourTagNames,
              dbo.getTagNames(i.imageid) as memberTagNames,max(weekNumber)-1 as lastWeek 

  from        images as i 

  left join   Imagerating as ir on i.imageId = ir.imageId

  left join   tag as t on i.imageId = t.imageId where 1=1 

  and         galleryName = 'pictures' 

  and         weekNumber = '4' 

  group by    i.imageId,GalleryName,Fullpath,MediumPath,ThumbPath,
              ViewCounter,i.DateCreated,ItemNumber,Gender,Minutes,Seconds,
              FramesPerSecond,WeekNumber,Filename,Size,FlvFilename,FlvSize,
              NumberOfMovies,Free,Comment 

  order by    filename

T-SQL不支持LIMIT.相反,请TOP在您的SELECT:

SELECT TOP 100 -- Rather than LIMIT 100 at the bottom
    Field1, Field2 -- etc.
FROM YourTable
GROUP BY Field1
ORDER BY Field2

如果您使用的是SQL Server 2012或更高版本,则可以使用OFFSET和FETCH [FIRST|NEXT]获取LIMIT分页结果集的功能.
