IDと名前を持つテストマスターテーブルがあります

TestMaster          
ID  Name        
1   a       
2   b       
3   c

そしてtesttransにはIDマスターID、開始日と終了日があります 

TestTrans           
ID  MasterID    Statusdate  Outcome
1   1   01/01/2013  Close
2   1   03/01/2013  Open
3   1   06/01/2013  Open
4   1   10/01/2013  Close
5   1   12/01/2013  Open
6   2   10/10/2012  Open
7   2   15/10/2012  Close
8   2   15/10/2012  Open
9   3   15/01/2013  Open
10  3   20/01/2013  Close
11   3  21/01/2013  Open
12  3        25/01/2013         Open

次のような出力が必要です
start date: should be statusdate of record
end date: should be based on the record status. ステータスがクローズの場合、終了日はクローズされたレコードのsatatusdateであり、クローズされたステータスより前のすべてのレコードは同じグループの一部とみなされます

Masetr ID でグループ化
