    FULL OUTER JOIN [DM_886_MarriottSocialData].[dbo].[DFA_BSE_DIS_CON_1] con
        ON cmg.PlacementID = con.PlacementID 
            AND cmg.DeliveryDate = con.ConversionDate 
            AND cmg.CampaignID = con.CampaignID 
            AND cmg.Country = con.Country 
            AND cmg.ADID = con.ADID 
            AND cmg.CreativeID = con.CreativeID 
            AND cmg.AdvertiserID = con.AdvertiserID 
WHERE cmg.DeliveryDate >= '2014-01-01' 
    AND cmg.DeliveryDate <= '2014-03-16'

This is the code I am using currently to evaluate aggregate table but i am getting 1900-01-01 default date in some records. however, i want those all records in final table. The reason is because of 1900-01-01 some columns are effecting with 5%-10% of fluctuation in their respective values.

Thanks
