    <p>I have 2 tables, ticket and ticket_custom.<br> Here are how the tables are set up.<img src="https://lh3.ggpht.com/_BExRqkFgz70/SfIKYSErMxI/AAAAAAAAAHk/pALtXucgIS8/howTablesAreDefined.jpg" alt="alt text"></p> <p>I have a web interface where I can change the state (value in the table ticket_custom) The web interface adds a new entry instead of updating the original entry. </p> <pre><code>ticket name value 1 state Ready for Final Verification 2 state Ready for Final Verification 1 state Verified </code></pre> <p>The last row is added</p> <p>So I need to modify the queries.</p> <pre><code> SELECT p.value AS __color__, id AS ticket, summary, component, version, c.value AS state, milestone, t.type AS type, owner, status, time AS created, changetime AS _changetime, description AS _description, reporter AS _reporter FROM ticket t, ticket_custom c LEFT JOIN enum p ON p.name = t.priority AND p.type = 'priority' AND id = c.ticket WHERE status &lt;&gt; 'closed' AND id = c.ticket ORDER BY CAST(p.value AS int), milestone, t.type, time, c.ticket </code></pre> <p>The query now returns both entries. I tried to add a nested select in the where clause. </p> <pre><code>SELECT g.ticket FROM ticket_custom g WHERE g.ticket = id ORDER BY g.ticket DESC LIMIT 1 </code></pre> <p>So -</p> <pre><code>SELECT p.value AS __color__, id AS ticket, summary, component, version, c.value AS state, milestone, t.type AS type, owner, status, time AS created, changetime AS _changetime, description AS _description, reporter AS _reporter FROM ticket t, ticket_custom c LEFT JOIN enum p ON p.name = t.priority AND p.type = 'priority' AND id = c.ticket WHERE status &lt;&gt; 'closed' AND id = c.ticket and ( SELECT g.ticket FROM ticket_custom g WHERE g.ticket = id ORDER BY g.ticket DESC LIMIT 1 ) ORDER BY CAST(p.value AS int), milestone, t.type, time, c.ticket </code></pre> <p>Clearly I'm doing something wrong. </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.
