Is there something you are not showing us? With what is given I don't see why you are trying to do with one sql statement. Just separate into individual statements as you are not saving any time. Also what are you joining on? Did you mean select * from reductions, surprimes?

Subject: SQL can I do this without 2 CTE?

Hi,

I have a transaction table with different rates that may be indicated by a flag as either a discount(reduction) or a premium(surprime).
I need the maximum of each type of rate.

I'm using

with
reductions as ( select max(rate) as max_reduction from mytable where reductionFlag = '1'),
surprimes as ( select max(rate) as max_surprime from mytable where surprimeFlag ='1')
select * from reductions join surprimes
;

But I wonder if there's a simpler way?

Thanks
