SET PASSWORD

Function

Change the user password.

Precautions

• If no user is specified, the password of the current user is changed.
• An initial user can change the password of any user (including its own password). REPLACE does not need to be specified to verify the current password.
• A non-initial user cannot change the password of an initial user.
• The sysadmin user and users with the createrole permission can change the passwords of other users (non-initialization, non-sysadmin, and non-createrole users). REPLACE does not need to be specified to verify the current password.
• When the sysadmin user or a user with the createrole permission changes the password, REPLACE must be specified to verify the current password.
