i wat ti find the max sales of every product which i want to
load into target table

Answer Posted / tdguy

Vaishnavi...i think the data presented here is already in a
reporting format...because sales amount for each month for
each prod id has been aggregated column wise. As far as I
know,any aggregate function like max,min,sum,count could
be applied only to row wise data. In case of manipulation
of column wise data, we may have to go with case statement
or we may have to transpose the column wise data to row
data for the manipulation to be done. So in this case,
either case statement has to be used for comparison of
column data or column to row transposition has to be done
by utilizing union statement(sel jan from table union sel
feb from table...till dec) and then the max value function
can be applied. Or if creation of volatile/temp tables is
allowed, then the above result can be stored temporarily
and manipulations can be done. Other option would be to
create UDF, but i think that has to be looped(thru SP i
think..not sure)...This is my opinion. Suggestions are
welcome.
