How do I append non-matching records

We're not there. We can't see your tables or relationships. Are you saying that you have two tables with identical structure, and you're adding to one table only if the record isn't already in another table? If so, why?! In a well-normalized relational database, you usually don't need/have multiple tables with the same structure. More info, please...
