 ## User Permission 
 When you add the data source, the database user you specify must only be granted SELECT permissions on the specified database and tables you want to query. Grafana does not validate that the query is safe. The query could include any SQL statement. For example, statements like `DELETE FROM user;`  and  `DROP TABLE user;`  will be executed. We **highly** recommend you create a specific Vertica user with restricted permissions.
