I want to share a “trick” on how to mark SQL Server user objects as deprecated. But first, why we need to mark an object as deprecated?
- code refactors
- object schema refactors
- mandatory backward compatibility in a multi customer scenario
We can use extended properties. They are a set of name/value properties in which you can specify custom value, with your own naming convention. Every SQL Server object can be, let’s say, extended using those properties. There are also three stored procedures which you can use in order to manage extended properties:
- sp_addextendedproperty – adds an extended property
- sp_dropextendedproperty – deletes an extended property
- sp_updateextendedproperty – updates an extended property
