    <p>In the dbase I 've few tables named as <code>aaa_9xxx, aaa_9yyy, aaa_9zzz</code>. I want to find all data with a specified <code>DATE</code> and show it with the <code>TIME ASC</code>.</p> <p>First, I must find a tables in the dbase:</p> <pre><code>$STH_1a = $DBH-&gt;query("SELECT table_name FROM information_schema.tables WHERE table_name LIKE 'aaa\_9%' "); foreach($STH_1a as $row) { $table_name_s1[] = $row['table_name']; } </code></pre> <p>Second, I must find a data wit a concrete date and show it with <code>TIME ASC</code>:</p> <pre><code>foreach($table_name_s1 as $table_name_1) { $STH_1a2 = $DBH-&gt;query("SELECT * FROM `$table_name_1` WHERE date = '2011-11-11' ORDER BY time ASC "); while ($row = $STH_1a2-&gt;fetch(PDO::FETCH_ASSOC)) { echo " ".$table_name_1."-".$row['time']."-".$row['ei_name']." &lt;br&gt;"; } } </code></pre> <p>.. but it shows the data sorted by tables name, then by <code>TIME ASC</code>. I must to have all this data (from all tables) sorted by <code>TIME ASC</code>.</p> <hr> <p>Thank You dev-null-dweller, Andrew Stubbs and Jaison Erick for your help. I test the Erick solution :</p> <pre><code>foreach($STH_1a as $row) { $stmts[] = sprintf('SELECT * FROM %s WHERE date="%s"', $row['table_name'], '2011-11-11'); } $stmt = implode("\nUNION\n", $stmts); $stmt .= "\nORDER BY time ASC"; $STH_1a2 = $DBH-&gt;query($stmt); while ($row_1a2 = $STH_1a2-&gt;fetch(PDO::FETCH_ASSOC)) { echo " ".$row['table_name']."-".$row_1a2['time']."-".$row_1a2['ei_name']." &lt;br&gt;"; } </code></pre> <p>it's working but I've problem with '<code>table_name</code>' - it's always the <code>LAST</code> table name.</p> <p>//----------------------------------------------------------------------</p> <p>...and the ending solution with all fixes, thanks all for your help, :))</p> <pre><code>foreach($STH_1a as $row) { $stmts[] = sprintf("SELECT *, '%s' AS table_name FROM %s WHERE date='%s'", $row['table_name'], $row['table_name'], '2011-11- 11'); } $stmt = implode("\nUNION\n", $stmts); $stmt .= "\nORDER BY time ASC"; $STH_1a2 = $DBH-&gt;query($stmt); while ($row_1a2 = $STH_1a2-&gt;fetch(PDO::FETCH_ASSOC)) { echo " ".$row_1a2['table_name']."-".$row_1a2['time']."-".$row_1a2['ei_name']." &lt;br&gt;"; } </code></pre>

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.
