I am going to be using merge replication in SQL 2012 for offline clients who can synchronise their data.
The merge replication process adds a guid to each table that is being replicated, but I am wanting to know how to add an additional int id as well?
For instance our clients ring up the support desk and they have to identify a particular record they don't want to have to deal with guids.
An identity column would be ideal, but how would this work with replication? Would each site have to have a different identity range?
The answer is here,

Basically each client is given two ranges. Once they have used up the first range and they sync they will be given a new range.
An error is thrown if an insert occurs in a table that has exceed both ranges. The only way this could happen is if a user inserts 2000 records before doing a sync. The range size can be increased if this is likely.
