Although I'm not yet in this problem, I just thought it would bite me someday. When I make a table on my database and at later date decided to update my database by adding table or adding/removing PK/FK relationship, why it doesn't allow the table to be changed and prompts me to just create a new table? I think this will be a big problem if I already deployed my website and at a later date, decided to add one or two columns. If I have to recreate a table, then all the tables requires to be recreated as well (if they have PK/FK relationship to the table you are planning to update). Any resolution on this one? Or is it really not allowed in SQL 2008. Didn't encounter such errors on MSSQL 2000 and 2005.
