-Summary:

Fix Bugzilla Bug 117641 Multiple grouping doesn't work correctly when data is grouped by interval

 

-Bugzilla Bug (s) Resolved:

Bugzilla bug 117641

 

-Description:

The former grouping algorithm sorts all columns before they are grouped. This is ok when the group unit is single rows. But when dealing with groups with intervals the algorithm would be of problematic.

 

Add some codes to CachedResultSet.java so that sort will not only being carried out before the grouping is done, but also will it being done during the grouping process so that the former group (if with intervals) will affect the sort of latter groups.

-Tests Description:
Unit test
