Move Field values in same table
I have a table with 3 fields, field1, field2 and field3. I need to write an update query that moves field2 to field1 AND if field3 is entered, move field3 to field1 (replacing value just moved from field2). How can I accomplish this by using coldfusion?

Question: Is there a way to consider 0 as a not-null expression? It works fine when the value is Null but not when value is 0. Please advice.

update yourtable
set field1 = coalesce(nullif(field3,0),
where ...
nullif ( a,b) returns null if a and b are equal... else a
set field1 = coalesce(nullif(field3,0),
where ...
nullif ( a,b) returns null if a and b are equal... else a
