    <p>As the title states, I'm switching from old MySQL_statements to PDO. I am having a problem however when trying to see if <code>'tableitem'</code> exists already, then if it does I want to grab <code>'tableitem2'</code>, and if the <code>'tableitem'</code> doesn't exist, I want to set <code>'tableitem2'</code> to 1. Here is my old MySQL code and below I will state what I have tried. </p> <pre><code>$user_ip = $_SERVER['REMOTE_ADDR']; $query = "SELECT * FROM TABLENAME WHERE user_ip='$user_ip' "; $result = mysql_query($query) or die(mysql_error()); $row = mysql_fetch_row($result); if (mysql_num_rows($result) ) { $_SESSION['stage'] = $row[1]; } else { $_SESSION['stage'] = 1; $strSQL2 = "INSERT INTO TABLENAME (user_ip, stage) VALUES ('$user_ip','$stage')"; $result = mysql_query($query) or die(mysql_error()); } </code></pre> <p>The above worked, but now I wish to switch to PDO statements. Here if what I have tried with PDO statements:</p> <pre><code>$user_ip = $_SERVER['REMOTE_ADDR']; $sql = "SELECT COUNT(`stage`) FROM `TABLENAME` WHERE `user_ip` = ?"; $result = $pdo-&gt;prepare($sql); $result-&gt;execute(array($user_ip)); $number_of_rows = $result-&gt;fetchColumn(); /* Check the number of rows that match the SELECT statement */ if ($result-&gt;fetchColumn() &gt; 0) { $_SESSION['stage'] = $row[1]; } else { $_SESSION['stage'] = 1; $result = $pdo-&gt;prepare("INSERT INTO `BPGUV` (`user_ip`, `stage`) VALUES (:user_ip, :stage)"; $result-&gt;execute( array( ':user_ip' =&gt; $user_ip, ':stage' =&gt; 1 ) ); } </code></pre> <p>Any help is much appreciated, I have connected to the database using PDO and am able to use MySQL commands using PDO, just can't seem to transfer the above code into PDO statements properly.</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.
