Microsoft® SQL Server 2012 Unleashed

What’s New in Creating and Managing Views

Much of the core functionality associated with standard views has remained unchanged in SQL Server 2012. There is, however, one feature that has been removed in SQL Server 2012 that could impact views. The use of *= and =* in your SQL statements including views has been discontinued in SQL Server 2012. The ANSI join syntax using the JOIN keyword should be used instead. If you have views that were created in an earlier version of SQL Server, make sure that these views are not using the *= or =* syntax.
