Re: SQL can I do this without 2 CTE?

[Luis Rodriguez <luisro58@xxxxxxxxx>]

Just a wild guess:

SELECT
max(
( Case reductionFlag = '1'
   Then rate
   else 0
 end)
 ) as maxreductions

max(
( CASE surprimeFlag = '1'
   THEN rate
   ELSE 0
 end)
 ) as maxsurprime

from mytable where (reductionFlag = '1' OR surprimeFlag ='1')
