CREATE WEAK PASSWORD DICTIONARY

Description

CREATE WEAK PASSWORD DICTIONARY creates a weak password dictionary, which is empty by default. You can use this syntax to add one or more weak passwords to the gs_global_config system catalog.

Precautions

  • Only the initial user, system administrator, and security administrator have the permission to execute this syntax.
  • Passwords in the weak password dictionary are stored in the gs_global_config system catalog.
  • The weak password dictionary is empty by default. You can use this syntax to add one or more weak passwords.
  • When a user attempts to execute this syntax to insert a weak password that already exists in the gs_global_config system catalog, only one weak password is retained in the system catalog.

Syntax

CREATE WEAK PASSWORD DICTIONARY        
       [WITH VALUES] ( {'weak_password'} [, ...] );

Parameters

  • weak_password

    Specifies a weak password.

    Value range: a string.
