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.
Only members of the sysadmin fixed server role can execute sp_addextendedproc.
The following example adds the xp_hello extended stored procedure.
USE master; GO EXEC sp_addextendedproc xp_hello, 'c:\xp_hello.dll';
