    <p>I'm trying to use the "HAVING" clause in a SQL query using the CakePHP paginate() method.</p> <p>After some searching around it looks like this can't be achieved through Cake's paginate()/find() methods. </p> <p>The code I have looks something like this:</p> <pre><code>$this-&gt;paginate = array( 'fields' =&gt; $fields, 'conditions' =&gt; $conditions, 'recursive' =&gt; 1, 'limit' =&gt; 10, 'order' =&gt; $order, 'group' =&gt; 'Venue.id'); </code></pre> <p>One of the $fields is an alias "distance". I want to add a query for when distance &lt; 25 (e.g. HAVING distance &lt; 25).</p> <p>I have seen two workarounds so far, unfortunately neither suit my needs. The two I've seen are:</p> <p>1) Adding the HAVING clause in the "group" option. e.g. <code>'group' =&gt; 'Venue.id HAVING distance &lt; 25'</code>. This doesn't seem to work when used in conjunction with pagination as it messes up the initial count query that is performed. (ie tries to <code>SELECT distinct(Venue.id HAVING distance &lt; 25)</code> which is obviously invalid syntax.</p> <p>2) Adding the HAVING clause after the WHERE condition (e.g. <code>WHERE 1 = 1 HAVING field &gt; 25</code>) This doesn't work as it seems the HAVING clause must come <strong>after</strong> the group statement which Cake is placing after the WHERE condition in the query it generates.</p> <p>Does anyone know of a way to do this with CakePHP's find() method? I don't want to use query() as that would involve a lot of rework and also mean I'd need to implement my own pagination logic!</p> <p>Thanks in advance</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.
