Could you please let me know why you have to use ODBC for Add new records and Update old records? why you can't use the same connection?
MS Sql connection uses bcp interface to load data into the database.
This interface was designed by Microsoft especially for fast data load.
Unfotuntately it is not posssible to use it to perform updates, therefore you have to use Odbc connection instead.
Can you select to skip ROWS from Execel before importing?
you can use filter for that
GetSystemVariable('RECORDNUMBER')>10
Could you please let me know if I can change this 0-42563-06804-2 into 042563068042 before importing
You can use calculated fields for that
Replace(String,OldPattern,NewPattern):String
