title: Retrieving data from two tables with sql
body: <p>I am not sure what I want to do is possible, but ...</p>
  
  <p>I have two tables that will be joined on a name field.  Each table will have the same respective fields however, the values may or may not be the same.  I would like a query that would pull only the rows where the respective field values are different.  I know I could do that with a long clause containing ORs and NOT EQUALs, but if for example, the table contained 15 fields, then this would not be fun.  Can you programmatically enumerate any number of fields and compare those fields for differences in values?</p>
