Newby DTS Question

Hi,

I am trying to set up a DTS Package to transfer data from a remote
MySQL server to a local MS SQL database. The source tables will remain
static as will the destination however I only want to copy down data
that does not already exist in the local database.

I have two different methods of which to identify the new rows, on some
tables it is by a unique ID thus in TSQL I would say WHERE ID x.
Other tables are by date where I would want to do something like WHERE
CreateDate >= GetDate()-1

How would I go about performing such clauses using DTS?

Thanks

Mike
