 [~dongjoon] and [~hyukjin.kwon] , I have checked this case in sparl-sql and i 
found we are allow to create temporary view with Negative scale *decimal(2, 
-2)*  and able to query the data from temporary table.

I think we should not allow to create view with negative scale *decimal(2, -2)*.

I have checked master branch behaviour and found during creation for temporary 
view data_type is showing *double*.

I think it's wrong.
