+          The database user should only be granted SELECT permissions on the specified database &amp; tables you want to
+          query. Grafana does not validate that queries are safe so queries can contain any SQL statement. For example,
+          statements like <code>USE otherdb;</code> and <code>DROP TABLE user;</code> would be executed. To protect
+          against this we <strong>Highly</strong> recommmend you create a specific MySQL user with restricted
