Create a unique index on the table:
CREATE INDEX (SQL Server Compact) | Microsoft Docs[^]

If the majority of values will be new, then just insert them and handle the constraint violation error which will be thrown when a duplicate value is inserted.

Otherwise, issue an UPDATE for the row and check the number of rows affected. If no rows were affected, issue an INSERT for the row.
