    <p>I got stucked with this query in the past couple of hours, and I badly need someone to help me figure it out. I'm try to finish my private message system, but I lost myself in the database tables. I've created three tables for the system, and they are as follows:</p> <pre><code>CONVERSATION(**conversation_id**, subject) CONVERSATION_MEMBER(**conversation_id**, **user_id**, conversation_last_view, conversation_deleted) CONVERSATION_MESSAGE(**message_id**, conversation_id, user_id, message_date, message_text) </code></pre> <p>Ok, so in my function to get all conversations of a specific user, I'm fetching the subject, the date, and at last I want to show the user who is he/she talking to. I wrote the following query:</p> <pre><code>SELECT c.conversation_id, c.conversation_subject, MAX(cmes.message_date) AS conversation_last_reply, FROM conversation c, conversation_member cmem, conversation_message cmes WHERE c.conversation_id = cmes.conversation_id AND c.conversation_id = cmem.conversation_id AND cmem.user_id = {$_SESSION['user_id']} AND cmem.conversation_deleted = 0 GROUP BY c.conversation_id ORDER BY conversation_last_reply DESC </code></pre> <p>And, at last I'm tryin to get the user's first and last name (the other user in the conversation), but I lost myself on how to do that. I've tried to create another function that will get the conversation id, while looping through the results of the first query, and return the user's first and last name, but it didn't work out.</p> <p>Btw, for the users I have another table... I guess I don't have to tell you. Ok, thank you.</p>

    2. COWhat do you want to say? I don't know how am I going to select anything, because I am doing cmem.user_id = sessionID. Would you like to tell something more on your answer?

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.
