Hello world 2013-03-28 22:34:14 ----------------------------- I don't feel very good today Hello world 2013-03-28 22:34:14 </code></pre> <p>what I want is, suppose the <code>I feel like s**t today</code> is the latest status, so it should output like:</p> <pre><code> I feel like s**t today!!!!

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.
