Hi Gregory,
i've put that () to the my stored proc and i've created myguid c(32) on my table and also allready set defauly value that () result = it works :) thanks

and additional question from me ,
i think i will use this field for data synchronization between tables for server and sales force laptops . how would be the your synchronization syntax for this ? and also datetime stamp is important . why probably may some records has been changed . syntax will check first if record on the server will copy it to the server table and second check will be if record exist but on the laptop tables record never than server table will update

how would be this ?

TIA
