Registers the name of a new extended stored procedure to Microsoft SQL Server.
This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Use CLR Integration instead.
After an extended stored procedure is created, it must be added to SQL Server by using sp_addextendedproc. For more information, see Adding an Extended Stored Procedure to SQL Server.
This procedure can be run only in the master database. To execute an extended stored procedure from a database other than master, qualify the name of the extended stored procedure with master.
sp_addextendedproc adds entries to the sys.objects catalog view, registering the name of the new extended stored procedure with SQL Server. It also adds an entry in the sys.extended_procedures catalog view.
Existing DLLs that were not registered with a complete path will not work after upgrading to SQL Server 2012. To correct the problem, use sp_dropextendedproc to unregister the DLL, and then reregister it with sp_addextendedproc, specifying the complete path.
The following example adds the xp_hello extended stored procedure.
USE master GO EXEC sp_addextendedproc xp_hello, 'c:\xp_hello.dll'
