Changing database options (Sybase Central)

Change the values of database options for a database, user, or role.

Prérequis

Any user can set their own options.

To set database options for other users or roles, including the PUBLIC role, you must have one of the following system privileges, depending upon which privilege the option requires:

  • SET ANY SYSTEM OPTION
  • SET ANY PUBLIC OPTION
  • SET ANY SECURITY OPTION
  • SET ANY USER DEFINED OPTION

Contexte et remarques

Changing the options for the database is equivalent to changing the options for the PUBLIC role.

Any option, whether user-defined or not, must have a PUBLIC setting before a user-specific value can be assigned. You can only create new options for the PUBLIC role.

Changing the value of an option for the PUBLIC role changes the value of the option for all users, except those who have explicitly set values for that option. When you set the value of an option for a user or role (other than the PUBLIC role), the new value overrides the value set by the PUBLIC role.

When you remove an option from a user or role, the PUBLIC setting for the option is applied. When you remove an option from the PUBLIC role, the option is removed from the database. All user settings for options must be removed before the option can be removed from the PUBLIC role.

You cannot set or change temporary options using Sybase Central. To set a temporary option, use the SET OPTION statement.
