    <p>I've got an unlisted Fusion Table with sample election data and vote counts by Wisconsin county, and I'm building a maps display page for election night. I'd like to conditionally style the county polygons depending on which candidate has a higher vote count, but I can't seem to do any styling based on a WHERE clause which directly compares column values. Instead, the default styling takes effect and the where clauses never kick in.</p> <p>My reading of the <a href="https://developers.google.com/fusiontables/docs/developers_reference#Select" rel="nofollow">FT "SQL-ish" syntax</a> makes me think that it doesn't allow a WHERE clause which directly compares two columns, so maybe that's what's stopping me ... but man, I'd very much like to. Is there a technique I'm missing?</p> <p>Vote counts for candidate 1 are in "1_Vote_Count" and for candidate 2 in "2_Vote_Count".</p> <pre><code> &lt;script type="text/javascript"&gt; function initialize () { var map = new google.maps.Map(document.getElementById('map-canvas'), { center: new google.maps.LatLng(44.824708,-89.780273), zoom: 7, mapTypeId: google.maps.MapTypeId.ROADMAP, streetViewControl: false, mapTypeControl: false, zoomControl: true, zoomControlOptions: { style: google.maps.ZoomControlStyle.SMALL }, panControl: false, }); var layer = new google.maps.FusionTablesLayer({ query: { select: 'geometry', from: '173CovMDpzEwyBBtF2fwkxHB5nt6zETzBzG-3YLE', where: "Office_ID = 'G' AND FIPS_Code &gt; 0" }, styles: [{ polygonOptions: { fillColor: "#00FF00", fillOpacity: 0.3, strokeWeight: 0.5 } }, { where: "'1_Vote_Count' &lt; '2_Vote_Count'", polygonOptions: { fillColor: "#DD0000" } }, { where: "'2_Vote_Count' &lt; '1_Vote_Count'", polygonOptions: { fillColor: "#0000DD" } }] }); layer.setMap(map); } &lt;/script&gt; </code></pre>

    1. COI think you are correct that it is not possible to compare two columns of your table. You could select the value first, but this is a very ugly solution.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
