UPSERT in SSIS

Question

I am writing an SSIS package to run on SQL Server 2008. How do you do an UPSERT in SSIS?

IF KEY NOT EXISTS
  INSERT
ELSE
  IF DATA CHANGED
    UPDATE
  ENDIF
ENDI         


        

Answer 1

Another way to create an upsert in sql (if you have pre-stage or stage tables):

--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))
