SQL将数据分组过后再分页怎么做？

[软软小面包]

我将数据使用
GROUP BY分组过后，由于有很多组，我想对这些组分页改怎么做？比如我每次之取5组数据，谢谢！

按group的字段row_number() over(partition by...)

这个说的好简洁呀

DECLARE @pageIndex INT,@pageSize INT
SET @pageIndex=1
SET @pageSize=3

SELECT * FROM (
	SELECT ROW_NUMBER() OVER (ORDER BY t.[type]) AS rid,t.[type]
	FROM (
		SELECT sv.[type] FROM MASTER.dbo.spt_values AS sv GROUP BY sv.[type]
	) AS t
) AS t WHERE rid BETWEEN (@pageIndex-1)*@pageSize AND @pageIndex*@pageSize

如果每组的数量不一怎么办？
