We have the query below running in a 9.2.0.6 DB
We put the query into a 9208 instance and the Distinct works, looks as
if there's a bug at play

SELECT shift.shiftid
           FROM job, shift, lkshiftmachinestage, operation
          WHERE job.actualstartdt <= shift.todt
            AND job.actualenddt >= shift.fromdt
            AND lkshiftmachinestage.machinestageid =
operation.machinestageid
            AND job.jobid = operation.jobid
            AND lkshiftmachinestage.shiftid = shift.shiftid
            AND shift.shiftid = 24548

And it returns 255 identical numbers. When I put in a distinct

SELECT DISTINCT shift.shiftid
           FROM job, shift, lkshiftmachinestage, operation
          WHERE job.actualstartdt <= shift.todt
            AND job.actualenddt >= shift.fromdt
            AND lkshiftmachinestage.machinestageid =
operation.machinestageid
            AND job.jobid = operation.jobid
            AND lkshiftmachinestage.shiftid = shift.shiftid
            AND shift.shiftid = 24548

I get "no rows found". Even tried making it a subquery

select distinct *

from

(

SELECT shift.shiftid

            FROM job, shift, lkshiftmachinestage, operation

           WHERE job.actualstartdt <= shift.todt

             AND job.actualenddt >= shift.fromdt

             AND lkshiftmachinestage.machinestageid =
operation.machinestageid

             AND job.jobid = operation.jobid

             AND lkshiftmachinestage.shiftid = shift.shiftid

             AND shift.shiftid = 24548

)
And still get nothing :-S
