    <p>I don't know of a single package that both queries MySQL and handles spatial data, but <a href="http://dev.mysql.com/doc/refman/5.0/en/supported-spatial-data-formats.html" rel="nofollow">MySQL supports</a> the <a href="http://en.wikipedia.org/wiki/Well-known_text" rel="nofollow">well-known-text</a> and <a href="http://en.wikipedia.org/wiki/Well-known_text#Well-known_binary" rel="nofollow">well-known-binary</a> spatial data formats (which will allow you to store points, lines, polygons, etc).</p> <p>You would need to make a query to your MySQL using <a href="http://mysql-python.sourceforge.net/MySQLdb.html" rel="nofollow">MySQLdb</a>, fetching the data with an SQL statement (<a href="http://dev.mysql.com/doc/refman/5.0/en/fetching-spatial-data.html" rel="nofollow">examples here</a>). If all you want is the points that make up a polygon, you can do some simple string manipulation to construct an array of points:</p> <pre><code>input = "POLYGON ((30 10, 10 20, 20 40, 40 40, 30 10))" def polygon_to_points(polygon): geometry = polygon[10:-2] coordinates = geometry.split(', ') coord_pairs = [] for c in coordinates: pair = c.split(' ') pair_num = [float(pair[0]), float(pair[1])] coord_pairs.append(pair_num) return coord_pairs </code></pre> <p>This returns <code>[[30.0,10.0],[10.0,20.0],[20.0,40.0],[40.0,40.0],[30.0,10.0]]</code> as intended. If you want to do some more complex spatial querying/analysis, take a look at the <a href="https://pypi.python.org/pypi/Shapely" rel="nofollow">Shapely</a> package.</p>

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.
