org.apache.derby.impl.sql.execute
Class DistinctGroupedAggregateResultSet  

java.lang.Object
  org.apache.derby.impl.sql.execute.BasicNoPutResultSetImpl
      org.apache.derby.impl.sql.execute.NoPutResultSetImpl
          org.apache.derby.impl.sql.execute.GenericAggregateResultSet
              org.apache.derby.impl.sql.execute.GroupedAggregateResultSet
                  org.apache.derby.impl.sql.execute.DistinctGroupedAggregateResultSet

All Implemented Interfaces:

org.apache.derby.iapi.sql.execute.CursorResultSet, org.apache.derby.iapi.sql.execute.NoPutResultSet, org.apache.derby.iapi.sql.ResultSet, org.apache.derby.iapi.store.access.RowLocationRetRowSource, org.apache.derby.iapi.store.access.RowSource

public class DistinctGroupedAggregateResultSet

extends GroupedAggregateResultSet

This ResultSet evaluates grouped aggregates when there is 1 or more distinct aggregate. It will scan the entire source result set and calculate the grouped aggregates when scanning the source during the first call to next(). RESOLVE - This subclass is essentially empty. Someday we will need to write additional code for distinct grouped aggregates, especially when we support multiple distinct aggregates.
