Counts the number of rows fetched from the JDBC result set.
This method delegates to the default RowSetIterator.
This method can be used to determine whether the View Object has read all the rows from the cursor. For example,getEstimatedRowCount returns an equivalent of count(*) on the View Object. The getFetchedRowCount() method returns the count of rows already fetched. If getFetchedRowCount() returns a value less than getEstimatedRowCount(), then the View Object has not read all rows from the cursor.
