data driven query DTS activeX script

Hi guys, im using this vb script.

'**********************************************************************
' Visual Basic Transformation Script
'************************************************************************

' Copy each source column to the destination column
Function Main()
DTSDestination("SES_STATUS") = DTSSource("Session Status")
DTSDestination("SIT_ID") = DTSSource("Year/Sitting")
DTSDestination("TUT_ID") = DTSSource("Tutor Code")
DTSDestination("SLC_ID") = DTSSource("Sub Location")
DTSDestination("SES_STREAM") = DTSSource("Stream")
DTSDestination("SES_TYPE") = DTSSource("Subject Type")
DTSDestination("SES_DATE") = DTSSource("Start Date")
DTSDestination("SUB_ID") = DTSSource("Subject Code")
DTSDestination("SES_ID") = DTSSource("Start Date")
Main = DTSTransformstat_InsertQuery
End Function

what I would Like to know is how can I complete this script so that it knows when to run an update statement and when to run a insert statement (I have already created the update and insert statements)

as this dts package will run every night and the source database tables are updated and inserted into quite regualar. So something like this is needed:

if record exists in destination
do update statement

if record not exist
do insert startement

many thanks in advance.

As far as I remember this is / was not possible. You should use an executeSQL tasks to UPDATE first the rows which are existing in both tables (Using linked servers or OPENDATASOURCE) and then Insert the remaining ones which are not in the destination table yet.
