Recently, this problem occurs in the development project. After a record is inserted, it immediately obtains its auto-increment ID in the database to process the associated data. How can this problem be solved? You can do this in SQL Server 2000 in several ways. For more information, see the following description and comparison.
1. The simplest way to obtain this ID is: (here is a simple and practical example)
