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

Another alternative would be to not use a temporary table but use a stored procedure with a table valued parameter. Pass a datatable to the sp and do the merge there.
