Triggers exist in SQL Server 2000 and there are no notes that state they will be obsoleted. No concrete feature sets have been released for the next version of SQL Server. However, the SQL Server team will not simply drop a feature from one version to the next, especially a feature that has been part of the product since its inception. How do you ensure RI? The ANSI standard is for RI to be enforced via foreign key constraints and this is the recommendation of Microsoft and MANY other database professionals. There is no reason to write large blocks of code to maintain RI when the database will already do that work simply by adding a foreign key constraint.
