Thats an interesting idea. What exactly do you script though? Things
like
(pseudo-code of course):

If SOURCETYPE = "AutoNumber" Then DESTTYPE = "int4" DESTDEFAULT = "nextval('record_id')"   EXECSQL "CREATE SEQUENCE
record_id"
End If

or have I got the wrong end of the stick completely?

PM: -------------
The scripting is used to convert one or more columns in the source into
a single column in the destination. You have one for each column.

ie:

Source        Destination

id    ---copy--->    id
date    -\________\    datetime
time    -/
name    ---copy--->    name

The copy bits aren't scripted but the middle one is.

Here, there's a script handling the conversion of date & time into a
single value.

I have a case of this here, where I use DTS to run dumpacl on our domain
controllers to return the security logs, and pipes the output through a
transform into a table. NT Events have two fields for the date, but I
need one, so the script for the above case is:

Function Main()DTSDestination("datetime") = DTSSource("date")+"
"+DTSSource("time")Main = DTSTransformStat_OK
End Function

Now that was a little bit of VB Script, but it could easily be Perl,
Javascript etc.
