how to filter out data by total value.

Hi expert,

       I have following requirement for a query:

         employee              overtime_reason_code        overtime_hours

               1                                      1                                       1

                                                       2                                       6

                                                       3                                       10

       so for an employee, if total overtime_hours>8, then it will be displayed in the report, otherwse , it will be filterred out from the report.

Many Thanks,
