How do I determine if a column is an identity column in MSSQL 2000?

Question

I want to do this in code, not with ALT+F1.

Answer 1

sp_help tablename 

In the output look for something like this:

 Identity     Seed     Increment     Not For Replication    
 -----------  -------  ------------  ---------------------- 
 userid       15500    1             0
