如果你知道这些部分是什么，你可以这样做:

select top 10 * from table where section=1
union
select top 10 * from table where section=2
union
select top 10 * from table where section=3

尝试了下面的方法，它也适用于领带。

SELECT rs.Field1,rs.Field2 
FROM (
    SELECT Field1,Field2, ROW_NUMBER() 
      OVER (Partition BY Section
            ORDER BY RankCriteria DESC ) AS Rank
    FROM table
    ) rs WHERE Rank <= 10

在T-SQL中，我会这样做:

WITH TOPTEN AS (
    SELECT *, ROW_NUMBER() 
    over (
        PARTITION BY [group_by_field] 
        order by [prioritise_field]
    ) AS RowNo 
    FROM [table_name]
)
SELECT * FROM TOPTEN WHERE RowNo <= 10

这适用于SQL Server 2005(编辑以反映您的澄清):

select *
from Things t
where t.ThingID in (
    select top 10 ThingID
    from Things tt
    where tt.Section = t.Section and tt.ThingDate = @Date
    order by tt.DateEntered desc
    )
    and t.ThingDate = @Date
order by Section, DateEntered desc

您可以尝试这种方法。 这个查询为每个国家返回10个人口最多的城市。

   SELECT city, country, population
   FROM
   (SELECT city, country, population, 
   @country_rank := IF(@current_country = country, @country_rank + 1, 1) AS country_rank,
   @current_country := country 
   FROM cities
   ORDER BY country, population DESC
   ) ranked
   WHERE country_rank <= 10;

我知道这个帖子有点老了，但我刚刚遇到了一个类似的问题(从每个类别中选择最新的文章)，这是我想出的解决方案:

WITH [TopCategoryArticles] AS (
    SELECT 
        [ArticleID],
        ROW_NUMBER() OVER (
            PARTITION BY [ArticleCategoryID]
            ORDER BY [ArticleDate] DESC
        ) AS [Order]
    FROM [dbo].[Articles]
)
SELECT [Articles].* 
FROM 
    [TopCategoryArticles] LEFT JOIN 
    [dbo].[Articles] ON
        [TopCategoryArticles].[ArticleID] = [Articles].[ArticleID]
WHERE [TopCategoryArticles].[Order] = 1

这与Darrel的解决方案非常相似，但克服了可能返回比预期更多行的RANK问题。
