Subj:   OLAP function and tracking data changes
 
From:   Alan.Chow

Hi,

Assuming I am given the following data:

     field1   field2   field3   field4   start_date   end_date
     ------   ------   ------   ------   ----------   --------
     1001     AAA      value3            01/01/2011   10/01/2011
     1001     AAA      value3   555      11/01/2011   22/01/2011
     1001     AAA      value3   11       23/01/2011   10/03/2011
     1001     BBB      value3   11       11/03/2011   08/05/2011
     1001     AAA      value3   11       09/05/2011   31/12/2999

I am interested in tracking the changes in the first 3 fields only, so I need to select from the table hoping to get a result as below:

     field1   field2   field3   start_date   end_date
     ------   ------   ------   ----------   --------
     1001     AAA      value3   01/01/2011   10/03/2011
     1001     BBB      value3   11/03/2011   08/05/2011
     1001     AAA      value3   09/05/2011   31/12/2999

but have not been successful. Would anyone know how ? Much appreciated.
