我试图弄清楚如何返回每组Trans.TranSID的前10个记录.

SELECT a.ABID, a.ABName, t.TranSID, SUM(IIF(TranTypeID = 'CO', td.Qty * CAST(td.Price AS money) * - 1, 
                      td.Qty * CAST(td.Price AS money))) AS TotalSales
FROM         Trans t INNER JOIN
                      TransDetail td ON t.TranID = td.TranID INNER JOIN
                      ABook a ON t.TranABID = a.ABID
WHERE     (t.TranDate BETWEEN CONVERT(DATETIME, '2012-01-01 00:00:00', 102) AND CONVERT(DATETIME, '2013-01-01 00:00:00', 102)) AND 
           t.TranTypeID in ('SO','CA','CO') AND (t.TranStatus <> 'V')
GROUP BY a.ABID, a.ABName, t.TranSID
HAVING  (NOT (a.ABName LIKE '%cash%'))
ORDER BY t.TranSID, TotalSales Desc

我可以在select语句中添加"TOP 10",但不管是哪个组,这都会给我前10个帐号.有25组Trans.TranSID,我试图获得每组的前10名.
