怎么样用一条语句取出每组除了第一条和最后一条数据的信息
题目：
表名 TEST

数据：
TID VID VName VNumber
1 1 AA 10
2 1 AA 8
3 1 AA 2
4 2 BB 90
5 2 BB 70
6 2 BB 20

要求按照VID 和 VName分组，取出数据：
TID VID Vname Vnumber
2 1 AA 8
5 2 BB 70

也就是取出每组除了开始一条和最后一条的其他所有信息。

SQL code

SELECT *FROM TB T1WHERE EXISTS(SELECT 1 FROM TB T2 WHERE T2.VID=T1.VID AND T2.VNAME=T1.VNAME AND T2.TID<T1.TID) AND EXISTS(SELECT 1 FROM TB T2 WHERE T2.VID=T1.VID AND T2.VNAME=T1.VNAME AND T2.TID>T1.TID)
