User Management

Admin permissions are needed to execute one of the following processes.

Creating user 'test' with password 'test'

> CREATE USER test test

As global permissions, you can set 'none', 'read', 'write', 'create' and 'admin':

Revoking all global permissions from user 'test'

> GRANT none TO test

Valid local permissions are 'none', 'read' and 'write':

Granting write permission on database 'factbook' to user 'test'

> GRANT write ON factbook TO test

Note: Local permissions overwrite global permissions. As a consequence, the 'test' user will only be allowed to access (i.e., read and write) the 'factbook' database. If no local permissions are set, the global rights are inherited.

Showing global permissions


Showing local permissions on database 'factbook'

> SHOW USERS ON factbook

Dropping of user 'test'

> DROP USER test

Permissions hierarchy

In the permission hierarchy the higher permission contains all underlying rights. For example if you have the permission 'write' you also have the permission 'read'.
