arial,helvetica,sans-serif;"><span style="font-family: arial,helvetica,sans-serif;">The query is to return an indicative value for each property for each station. The left outer join is required to ensure all station records are returned, whether or not there is a nearby value for any property.</span><br style="font-family: arial,helvetica,sans-serif;"><br style="font-family: arial,helvetica,sans-serif;"><span style="font-family: arial,helvetica,sans-serif;">The notice message only occurs when an outer join is specified, if it is not an outer join, then no message appears. The query appears to work fine, but I don't know the significance of the message, or what I have done to cause it. I figure that being a notice, rather than error or warning, it is not critical, but....<br><br><br>Any advice appreciated...<br><br> Brent Wood<br style="font-family: arial,helvetica,sans-serif;"></span><br style="font-family:
