Distinct of all the fields in the attribute view

Hi ,

I want to get the distinct values of the all the fields in the Attribute view.   I am not getting the distinct option either in Attribute view or calucation view.

My requirement is like this :

SELECT

    distinct

    'Y' as PRD_TYPE,

D_TIME_PERIOD.YEAR as PRD_YEAR,

D_TIME_PERIOD.YEAR as PRD_NUM,

D_TIME_PERIOD.YEAR_NAME as PRD_NAME

FROM

ABC.D_TIME_PERIOD D_TIME_PERIOD.

For the above schema we will get duplicate values .

I need to use same table in the analytical view. If I have duplicate values it misleads the result while joining .

Please help me how to get distinct for the above query in the attribute view.

Thanks & Regards,

Ramana.
