这是此处问题的扩展：My first complex SQL queries
我现在想删除'WHERE MatchID = 9000'条件，并返回显示第一行数据（如前所述）的结果表，但是对于每个单独的MatchID。结果数据应如下所示：
MatchID WhenOddsTaken MarketName Outcome Odds NumberOfBets VolumeMatched InPlay
9000 2011-09-17 14:01:02.000 Match Odds The Draw 3.95 2 94.28 1
9001 2011-09-17 14:04:38.000 Match Odds The Draw 4.40 179 17707.36 0
9002 2011-09-17 14:03:55.000 Match Odds The Draw 3.50 12 530.99 1
9003 2011-09-17 14:02:18.000 Match Odds The Draw 3.50 6 99.55 1
9004 2011-09-18 14:02:12.000 Match Odds The Draw 3.85 581 53612.29 0
以下是我正在使用的表格中的一些示例数据：
