    <p>I have a page where the latest status updates by my friends and me are displayed.</p> <p>The tables involved are statusUpdates, users &amp; friends.</p> <p>The script I used to pull the necessary data was -</p> <pre><code>$myQuery = mysql_query("SELECT * FROM statusUpdates AS su LEFT JOIN friends AS fr ON fr.frContactID = su.authorID JOIN (users AS u) ON (u.roll = su.authorID) WHERE (fr.frHostID = ".$userLoggedIn['roll']." or su.authorID = ".$userLoggedIn['roll'].") GROUP BY su.statusID ORDER BY su.statusID DESC LIMIT 0,15"); </code></pre> <p>And I printed the data using this -</p> <pre><code>if (mysql_num_rows($myQuery) == 0) echo "No updates to show"; else { while ($row = mysql_fetch_assoc($myQuery)) { // Print $row['statusID'], $row['status'], $row['authorID'], $row['fullName'], $row['userProfileLink'], etc } } </code></pre> <p>Now I am also thinking of incorporating a commenting system. For that I will be creating a new table <strong>comments</strong> with the following fields - <code>commentID, targetStatusID, commentorID, comment, commentTimeStamp</code></p> <p>How should I adjust my mysql queries so that the comments for each status update also get printed out in the following way -</p> <pre><code>status1 - comment1 - comment2 - comment3 [text field for new comment to status1] status2 - comment1 [text field for new comment to status2] status3 [no comments for this post] [text field for new comment to status3] status4 - comment1 - comment2 [text field for new comment to status4] [no more posts to show] </code></pre> <p>Please note that -</p> <p><strong>commentID</strong> is the primary key. <strong>targetStatusID</strong> indicates the particular status update on which the comment was made. <strong>commentorID</strong> is the ID of the person who commented. <strong>comment</strong> is the actual content. <strong>commentTimeStamp</strong> shows the time when the comment was made.</p> <p>By the way, I would like to achieve the whole thing using procedural programming, and <em>not OOP</em>.</p> <p>One of the ways to solve this would be by using a query inside while <code>($row = mysql_fetch_assoc($myQuery))</code> to select comments for <code>$row['statusID']</code>.</p> <p>But that would build up the number of queries if I wanted to display many posts.</p> <p>So what should my approach be?</p> <p>P.S. I came across similar questions, but none of their answers solved my issue.</p>

    1. CONote that mysql_* functions are depracted and will be removed in future. You should use [mysqli](http://php.net/manual/en/book.mysqli.php) or [PDO](http://php.net/manual/en/book.pdo.php)

    3. COas for your question you can make another kind of function whre you would pass ID of status and then return the comments. You would call this function in your while loop

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.
