Multiply of both partitions(years and months between 1900-01-01 and current)will exceed teradata limit of total no of partition 65535.

To me extract month of each year as a separate column say year_month. Now give case for each 12 month.


        a BETWEEN DATE '1900-01-01' AND '2011-01-01'
        EACH INTERVAL 1 year,  NO RANGE)
        , CASE_N( year_month = 'jan' , year_month = 'feb',etc
        ,  NO CASE, UNKNOWN) )
