RENAME USER
Syntax
The RENAME USER
statement renames existing MariaDB accounts. To use it, you must have the global CREATE USER
privilege or the UPDATE
privilege for the MariaDB
database. An error occurs if any old account does not exist or any new account exists. Each account name uses the format described in , "Specifying Account Names". For example:
RENAME USER 'jeffrey'@'localhost' TO 'jeff'@'127.0.0.1';
If you specify only the user name part of the account name, a host name part of '%'
is used.
RENAME USER
causes the privileges held by the old user to be those held by the new user. However, RENAME USER
does not automatically drop or invalidate databases or objects within them that the old user created. This includes stored programs or views for which the DEFINER
attribute names the old user. Attempts to access such objects may produce an error if they execute in definer security context. (For information about security context, see , "Access Control for Stored Programs and Views".)
The privilege changes take effect as indicated in , "When Privilege Changes Take Effect".
