		<h5>User Permission</h5>
		<p>
			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 permissions.

			Checkout the <a class="external-link" target="_blank" href="http://docs.grafana.org/features/datasources/mysql/">MySQL Data Source Docs</a> for more information.
