This is one of the common question in SQL Server 2000 DBA interview. How to add a column to a replicated / published table ? The answer is use sp_repladdcolumn and sp_repldropcolumn. If we get this question now, we may ask which version of sql server is this? Since SQL Server 2005 you may use simple DDL command like ALTER to add or drop a column from a published table (of course condition applies (***) like if the subscriber republishes the data then you should use the system sps). In SQL Server 2008 these system sps are deprecated, so you will not have this in next version.
