    <p>How do I get data out of SimpleDB? All I wanted to do was put data in and then get data out. It looks like the data is not easy to get out and in the end will require computing power to extract by looping etc. Am I correct?</p> <p>Here is my code to extract the data:</p> <pre><code>&lt;?php // Include the SDK require_once 'sdk.class.php'; // Instantiate $sdb = new AmazonSDB(); $select_expression = 'SELECT * FROM ' . $domain_name; $next_token = null; do { if ($next_token) { $response = $sdb-&gt;select($select_expression, array( 'NextToken' =&gt; $next_token, )); } else { $response = $sdb-&gt;select($select_expression); } // Get Data for row $body = $response-&gt;body-&gt;to_array()-&gt;getArrayCopy(); echo "ID: " . $msgId . "&lt;br&gt;"; $next_token = isset($response-&gt;body-&gt;SelectResult-&gt;NextToken) ? (string) $response-&gt;body-&gt;SelectResult-&gt;NextToken : null; } while ($next_token); echo "&lt;br&gt;"; ?&gt; </code></pre> <p>Here is the extract of the data I'm trying to extract.</p> <pre><code>Array ( [@attributes] =&gt; Array ( [ns] =&gt; http://sdb.amazonaws.com/doc/2009-04-15/ ) [SelectResult] =&gt; Array ( [Item] =&gt; Array ( [0] =&gt; Array ( [Name] =&gt; 1 [Attribute] =&gt; Array ( [0] =&gt; Array ( [Name] =&gt; msgAddress [Value] =&gt; +2782555555 ) [1] =&gt; Array ( [Name] =&gt; msgType [Value] =&gt; S ) [2] =&gt; Array ( [Name] =&gt; msgSubmitDate [Value] =&gt; 2012-09-02 15:48:46 ) [3] =&gt; Array ( [Name] =&gt; msgText [Value] =&gt; Test SMS message for ID no 1 ) ) ) [1] =&gt; Array ( [Name] =&gt; 2 [Attribute] =&gt; Array ( [0] =&gt; Array ( [Name] =&gt; msgAddress [Value] =&gt; +27825555555 ) [1] =&gt; Array ( [Name] =&gt; msgType [Value] =&gt; P ) [2] =&gt; Array ( [Name] =&gt; msgSubmitDate [Value] =&gt; 2012-09-02 15:48:46 ) [3] =&gt; Array ( [Name] =&gt; msgText [Value] =&gt; Test phone message for ID no 2 ) ) ) [2] =&gt; Array ( [Name] =&gt; 3 [Attribute] =&gt; Array ( [0] =&gt; Array ( [Name] =&gt; msgAddress [Value] =&gt; name@domain.co.za ) [1] =&gt; Array ( [Name] =&gt; msgType [Value] =&gt; E ) [2] =&gt; Array ( [Name] =&gt; msgSubmitDate [Value] =&gt; 2012-09-02 15:48:46 ) [3] =&gt; Array ( [Name] =&gt; msgText [Value] =&gt; Test email message for ID no 3 to name@domain.co.za ) ) ) [3] =&gt; Array ( [Name] =&gt; 4 [Attribute] =&gt; Array ( [0] =&gt; Array ( [Name] =&gt; msgAddress [Value] =&gt; andrebruton ) [1] =&gt; Array ( [Name] =&gt; msgType [Value] =&gt; P ) [2] =&gt; Array ( [Name] =&gt; msgSubmitDate [Value] =&gt; 2012-09-02 15:48:46 ) [3] =&gt; Array ( [Name] =&gt; msgText [Value] =&gt; Test push notification message for ID no 4 ) ) ) ) ) ) </code></pre> <p>All I want to get is the following variables:</p> <p>msgId (the Name), msgType, msgAddress, msgText, msgSubmitDate</p> <p>If I can get it using $msgType = Body->SelectResult->Item->Name or something like that.</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.
