sp_dropextendedproc [ @functname = ] 'procedure' 

[ @functname =] 'procedure'

Is the name of the extended stored procedure to drop. procedure is nvarchar(517), with no default.

0 (success) or 1 (failure)

Executing sp_dropextendedproc drops the user-defined extended stored procedure name from the sys.objects catalog view and removes the entry from the sys.extended_procedures catalog view. This stored procedure can be run only in the master database.

In SQL Server 2016 sp_dropextendedproc does not drop system extended stored procedures. Instead, the system administrator should deny EXECUTE permission on the extended stored procedure to the public role.

sp_dropextendedproc cannot be executed inside a transaction.

Only members of the sysadmin fixed server role can execute sp_dropextendedproc.

The following example drops the xp_hello extended stored procedure.


This extended stored procedure must already exist, or the example will return an error message.

USE master;
EXEC sp_dropextendedproc 'xp_hello';
