field differences

I have two tables one that has new data monthly and the other a back up of it. I have renamed last months, how do i create a query that will tell me if any data in any field changed  value?

so [currentmonth].[field1] =[lastmonthsbackup].[field1] no change
 [currentmonth].[field2]<>[lastmonthsbackup].[field2] data changed so row returned

the two tables are obviously identicle in structure.
