DROP CLIENT MASTER KEY

Description

Deletes a 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 be used to delete the metadata information recorded in the system catalog of the database, but cannot be used to delete the CMK file. You need to use keytool to delete the CMK file.
