| Data:
| sub mgr startdate enddate
| --- --- --------- -------
| 100 1 2003-01-01 2003-03-15
| 100 1 2003-03-15 2003-11-30
| 200 1 2003-01-01 2003-07-01
| 200 2 2003-07-01 2004-01-01
| 200 1 2004-01-01 2004-02-01
| 210 1 2003-01-01 2003-06-01
| 210 1 2003-06-01 2003-10-01
| 210 2 2004-01-01 2004-02-01
| 210 3 2004-02-01 2004-03-01
| 210 2 2004-03-01 2004-04-01
| 210 2 2004-04-01 2004-05-01
| 210 2 2005-05-01 2005-06-01

| Wanted result:
| sub mgr startdate enddate
| --- --- --------- -------
| 100 1 2003-01-01 2003-11-30
| 200 1 2003-01-01 2002-07-01
| 200 2 2003-07-01 2004-01-01
| 200 1 2004-01-01 2004-02-01
| 210 1 2003-01-01 2003-10-01
| 210 2 2004-01-01 2004-02-01
| 210 3 2004-02-01 2004-03-01
| 210 2 2004-03-01 2005-06-01

| It seems simple but without using cursors I don't see any solution.
| Can someone sort this out ?
| Any help is very much appreciated. Thanks.
