I needed to create a stored procedure today that could be used on any database within a given SQL Server instance. After some digging I found that there are three requirements for such a stored procedure:
- The stored procedure must be created in the master database.
- The name of the stored procedure must start with “sp_“.
- The stored procedure must be marked as a system object.
The first two are quite easily accomplished but the third requirement requires the use of an undocumented stored procedure named sys.sp_MS_marksystemobject which will mark the created stored procedure as a system object.
After you complete the above three steps, you can run the stored procedure on any of the databases found in that instance of SQL Server.
Note: If you need to “unmark” the procedure as a system object just simply drop the procedure and recreate it.
