hejian commented on KYLIN-3966:
-------------------------------

i think the measure columns can not be used directly without any measuring expression that

> When i try to multiply or divide 2 metric columns in a query
> eg: select col1*col2 from table 
> select col1/col2 from table.
> it throws the following errors
> That both of the two sides of the BinaryTupleExpression own columns is not supported
for * while executing SQL
> That both of the two sides of the BinaryTupleExpression own columns is not supported
for / while executing SQL.
> But when i use the + or - operators in the query it seems to be working fine.
> Is there any way to support these 2 operators as well?
> Thanks,
