    <p>If you are looking for displaying the count for each of the property values the <code>partments</code>, <code>houses</code>, <code>freeholds</code>, you should add a <code>GROUP BY property_type</code></p> <pre><code>SELECT property_type, COUNT(*) FROM $wpdb-&gt;postmeta WHERE meta_value BETWEEN 50000 AND 74999 GROUP BY property_type </code></pre> <p><strong>Update:</strong> You have to <em>pivot</em> your rows into columns in order to get the data the way you described like so:</p> <pre><code>SELECT t.property_type, COUNT(t.post_id) AS 'type count' FROM ( SELECT t.post_id, MAX(CASE WHEN t.meta_key = 'property_type' THEN t.meta_value END) AS property_type, MAX(CASE WHEN t.meta_key = 'price' THEN CAST(t.meta_value AS DECIMAL) END) AS Price FROM postmeta t GROUP BY t.post_id ) t WHERE t.property_type = 'apartment' AND t.Price BETWEEN 600000 AND 700000 GROUP BY t.property_type </code></pre> <p>Note that the <code>meta_value</code> field is supposed to store both a string values for property types as well as numeric values for <code>price</code>s so I <code>CAST</code> it to <code>DECIMAL</code> in order to select it as numeric data type so that you can perform calculation on it later on. I also used <code>MAX</code> as an aggregate function as a work around to pivot the rows.</p> <p>Here is a <a href="http://sqlfiddle.com/#!2/59a1d/5" rel="nofollow noreferrer"><strong>demo in SQL fiddle</strong></a>.</p> <p>This what you usually encounter in such a design model which is what they called <a href="http://en.wikipedia.org/wiki/Entity%E2%80%93attribute%E2%80%93value_model" rel="nofollow noreferrer"><strong>Entity–attribute–value model</strong></a>.

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.
