    I figured it out, for the commandText for the AdoNetAppender I set the command text to:

    <commandText value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message],[Exception]) VALUES (@log_date, @thread, @log_level, @logger, @message, @exception); DELETE FROM [Log] WHERE [Date] &lt; DATEADD(dd, -28, GETDATE())" />

    It feels hacky, but it works. I’ll post here if I find a neater solution.
