I am attempting to get the greatest value from this part of a query:
greatest((follette_title.usedbuying_price *1.37) or
(amtext.price*1.37) or
(nebraska.price *1.2) or
(tichenor.price *1.25))
My issue is there are null values in the tables, so this only returns null. How do I get around this without running an update on all the tables to change the null values to 0?
