i'm creating a qvd from a fact table that has multiple date dimensions associated with it.
I want to do a couple of things.
- Pull only the dates I will be loading from the fact table which I can do with the following query.
- Display only the distinct Years from those dates to the users.
The problem is that these are actually different dimension keys so I will get duplicate years.
Is there a way to extract just the unique years but still have the dim keys to associate with the model?
select distinct wpdd.plcy_dt_dim_key, PLCY_DT_YR_YY as "Policy Year",wpdd.*
From AWH.WR_MTD_COMB_DTL_F wmcdf, AWH.WR_VAL_DT_D, awh.wr_plcy_dt_d wpdd
where wmcdf.VAL_DT_DIM_KEY = WR_VAL_DT_D.VAL_DT_DIM_KEY
and wpdd.plcy_dt_dim_key = wmcdf.plcy_dt_dim_key
and AWH.WR_VAL_DT_D.VAL_DT_DAY_MDY >= '01-JAN-2013'
and AWH.WR_VAL_DT_D.VAL_DT_DAY_MDY <= '01-JAN-2018'
order by 2
