    <p>I have a Physician Query:</p> <pre><code>// Primary Physician Query $qPhysician = mysql_query("SELECT * FROM physicians ORDER BY lastName ASC, firstName ASC"); $rowPhysician = mysql_fetch_array($qPhysician); // State Query for Physician $idStatePhysician = $rowPhysician['idstate']; $qStatePhysician = mysql_query("SELECT * FROM states WHERE idstate=$idStatePhysician"); $rowStatePhysician = mysql_fetch_array($qStatePhysician); // City Query for Physician $idCityPhysician = $rowPhysician['idcity']; $qCityPhysician = mysql_query("SELECT * FROM cities WHERE idcities=$idCityPhysician"); $rowCityPhysician = mysql_fetch_array($qCityPhysician); </code></pre> <p>I have a while loop to display all physicians row to a table:</p> <pre><code>$num = mysql_num_rows($qPhysician); $i=0; while($i &lt; $num) { $idphysicians = $rowPhysician['idphysicians']; if ($i % 2 == 0){ echo "&lt;tr class='even' onclick=\"DoNav('physicianUpdate.php?idphysicians=$idphysicians');\"&gt;"; } else{ echo "&lt;tr class='odd' onclick=\"DoNav('physicianUpdate.php?idphysicians=$idphysicians');\"&gt;"; } echo "&lt;td&gt;" . mysql_result($qPhysician,$i,"lastName") . "&lt;/td&gt;"; echo "&lt;td&gt;" . mysql_result($qPhysician,$i,"firstName") . "&lt;/td&gt;"; echo "&lt;td&gt;"; if(isset($rowPhysician['idcity'])){echo mysql_result($qCityPhysician,$i,"name");} else{} echo "&lt;/td&gt;"; $i++; } </code></pre> <p>My problem is: I have 3 rows of data from my physicians table. Each has a value for 'idcity' reflecting the idnumber from my City table. However, the 1st row of Data displays the idcity=Name properly, but the 2nd and 3rd row gave an error:</p> <pre><code>Warning: mysql_result() [function.mysql-result]: Unable to jump to row 1 on MySQL result index 7 in C:\wamp\www\iPOC\physicians.php on line 55 </code></pre> <p>Also, if I have a blank value for idcity on one of the row, it also generates an error.</p> <p>Please help! 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.
