AnalyticDB for MySQL allows you to grant different permissions on different levels to implement permission control.

Permission levels

An AnalyticDB for MySQL cluster supports the following levels of permission control:

  • GLOBAL: cluster-level permissions
  • DB: database-level permissions
  • TABLE: table-level permissions
  • COLUMN: column-level (field) permissions

    If you want a user to query the data of one specific column in a table, you can grant the SELECT permission on the column to the user. Example: GRANT select (customer_id) ON customer TO 'test321'.
