web2py is always backward compatible, you can use either row.update or
row.update_record
but if you use db(db.cdsdata.id>0).select('extracted') you can't use
update_record because your rows didn't received an id from db
so you ca use any of this

rows=db(db.cdsdata.id>0).select()
rows=db(db.cdsdata.id>0).select(db.cdsdata.ALL)

or  just id and extracted if you are not going to use other fields

rows=db(db.cdsdata.id>0).select(db.cdsdata.id, db.cdsdata.extracted)
