Hi I’m using ms2005 for a simple calendaring system. We have three ‘legacy’ tables: Groups, Units and Staff.
I need to give each record in the tables a unique identifier (carrying across all 3 tables).
What would be best way to approach this? I am using NHibernate and was was wondering whether that could do it for me.
Anyway, any nods in the right direction much appreciated.
The usual practice is to create a surrogate primary key on each table using an int with IDENTITY(1,1).
If you need a unique values across systems then use a UNIQUEIDENTIFIER column (GUID).
