+This example shows how to drill down using array notation plus dot notation in features[0].`properties`.MAPBLKLOT to get the MAPBLKLOT property value in the San Francisco city lots data. Note that the word 'properties' is a Drill SQL keyword, so must be surrounded by back-ticks:
 
-    SELECT features[0].properties.MAPBLKLOT, FROM dfs.`/Users/drilluser/citylots.json`;
+    SELECT features[0].`properties`.MAPBLKLOT, FROM dfs.`/Users/drilluser/citylots.json`;
