Any way to SQLBulkCopy “insert or update if exists”?

Question

I need to update a very large table periodically and SQLBulkCopy is perfect for that, only that I have a 2-columns index that prevents duplicates. Is there a way to use SQLB

Answer 1

Not in one step, but in SQL Server 2008, you could:

• bulk load into staging table
• apply a MERGE statement to update/insert into your real table
