DROP SERVER

Description

Drops an existing data server.

Precautions

Only the server owner or a user granted with the DROP permission can run the DROP SERVER command. System administrators have this permission by default.

Syntax

DROP SERVER [ IF EXISTS ] server_name [ { CASCADE | RESTRICT } ] ;

Parameters

• IF EXISTS

  Reports a notice instead of an error if the specified data server does not exist.

• server_name

  Specifies the name of the data server to be dropped.

• CASCADE | RESTRICT
  • CASCADE: automatically drops the objects that depend on the data server.
  • RESTRICT: refuses to drop the server if any objects depend on it. This is the default action.
