Description

The rule "Deprecated system tables and views should not be used" states that any system tables or views that have been marked as deprecated, or are no longer supported, should not be used by developers when writing SQL Server code. This rule is important because deprecated system tables and views can contain outdated or inaccurate data, and using them in code can lead to unexpected results or errors. Additionally, using deprecated system tables and views can also cause performance issues if the code is not optimized properly.
