Both left and right aliases encountered in Hive JOIN; without any inequality clause

Question

I am using following query:

Select
   S.MDSE_ITEM_I,
   S.CO_LOC_I,
   MAX(S.SLS_D) as MAX_SLS_D,
   MIN(S.SLS_D) as MIN_SLS_D,
   sum(S.SLS_UNIT_Q) as SLS_UNIT_         


        

Answer 1

The problem I see with this approach is that, because there is a left outer join, that means we want to have all registers from left table just once, if we move the conditions to where clause, then those registeres where right table columns are null are lost.
