		<h5>User Permission</h5>
		<p>
			The database user should only be granted SELECT permissions on the specified database and 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
			<emphasis>highly</emphasis> recommmend you create a specific MS SQL user with restricted permissions.
