All tables should have a primary key, because if you ever need to update or delete a record you need to know how to uniquely identify it. A surrogate key is an artificially generated key. They're useful when your records essentially have no

问题 I have a minor, one line change (fixing a typo in a string), to a stored procedure that I would like to deploy to our production SQL Server 2005 server as soon as possible. The worry I have is what happens if at the exact time run the alter statement to update my stored procedure, it happens that something calls that stored procedure at the same time? Does it run with the previous copy of the stored procedure, or can it result to some corruption or errors? Considering the ACID nature of SQL
