Question

How would I go about getting a value from a column in a table and compare it to a column in another table and return the greater of the two in a single query?

I have two different queries for getting those values, I just don’t know how to compare:

select level from cmh where user = 'blah'
select level from cons where user = 'blah'

I need to compare the above two levels and get the greater of the two.

thanks

Something like (off the top of my head)

select
case when cmh.level > cons.level 
then cmh.level
else cons.level
end
from cmh inner join cons on cmh.[user] = cons.[user]
where cons.[user] = 'blah'
