Basically, you are looking to “Upsert” your data into the database. Here is a simple look up upsert example. With as few of records in your dataset as you have said, this method will suffice. With larger datasets, you probably want to look into using temp tables and using sql logic similar to this:

--Insert Portion
INSERT INTO FinalTable
( Colums )
SELECT T.TempColumns
FROM TempTable T
WHERE
(
    SELECT 'Bam'
    FROM FinalTable F
    WHERE F.Key(s) = T.Key(s)
) IS NULL

--Update Portion
UPDATE FinalTable
SET NonKeyColumn(s) = T.TempNonKeyColumn(s)
FROM TempTable T
WHERE FinalTable.Key(s) = T.Key(s)
    AND CHECKSUM(FinalTable.NonKeyColumn(s)) <> CHECKSUM(T.NonKeyColumn(s))
