DROP CLIENT MASTER KEY

Function

DROP CLIENT MASTER KEY deletes a client master key (CMK).

Precautions

• Only the CMK owner or a user who has been granted the DROP permission can run this command. By default, the system administrator has this permission.
• This command can only delete the metadata of key objects recorded in the system catalog of the database, but cannot delete the key entities managed by the client key tool or online key service.

Syntax

1

DROP CLIENT MASTER KEY [ IF EXISTS ] client_master_key_name [CASCADE];

Parameter Description

• IF EXISTS

  If a specified CMK does not exist, a notice rather than an error is issued.

• client_master_key_name

  Name of a CMK to be deleted.

  Value range: a string. It is the name of an existing CMK object.

• CASCADE
  • CASCADE: automatically deletes objects that depend on the CMK.
