exist for the emailaddress dont update data else create a user and update its profilexml from data fecthed from gedcom. for this i think i need some soln by which i can do only one roundtrip to database and can update all user's xml. or i can execute one sp to get userid from all users where i'll check if user exist then return userid else insert basic data and return inserted userid then for every user make xml from data and update it. please provide be suggestion what is best practice to do this kind of development. if need any more details please write me
