    <p>I am attempting to populate a list of records within the last X seconds of the server time.</p> <p>My current query is..</p> <pre><code>mysql_query("SELECT player.name FROM player, spectate WHERE (player.pid = spectate.player) &amp;&amp; spectate.bid=$bid"); </code></pre> <p>This works currently to retrieve all entries. My first thought was to select the time field as well. And then use the mktime() function to find the time difference with the current server time, and only print records with a small difference.</p> <p>But I figured that it would be more effective to include WHERE ($x > $servertime - spectate.time + 1) along with my other statements.</p> <p>It doesn't work as I have it now what am I doing wrong?</p> <p><strong>Function with SELECT</strong></p> <pre><code>function spectateJSON() { $servertime = date("Y-m-d H:i:s"); global $json, $bid; $specResult = mysql_query("SELECT player.name FROM player, spectate WHERE (player.pid = spectate.player) &amp;&amp; spectate.bid=$bid &amp;&amp; (20 &gt; $servertime - spectate.time + 1)"); $specResultCount=mysql_num_rows($specResult); $json.= '"spectate":['; for($i=0; $i&lt;$specResultCount; $i++) { $spectatorName=mysql_result($specResult,$i,"name"); $json.='"'.$spectatorName.'"'; if($i+1 != $specResultCount)$json.=","; } $json.=']'; } </code></pre> <p><strong>function with UPDATE or INSERT</strong></p> <pre><code>if(isset($_SESSION['char'])) { $charId = $_SESSION['char']; $bid = $_GET['bid']; $servertime = date("Y-m-d H:i:s"); $specResult = mysql_query("SELECT player FROM spectate WHERE player='$charId'"); $specResultCount=mysql_num_rows($specResult); if($specResultCount &gt; 0) { $Query=("UPDATE spectate SET bid='$bid' time='$servertime' WHERE player='$charId'"); mysql_query($Query); } else { mysql_query("INSERT INTO spectate (bid, player, time) VALUES ('$bid','$charId','$servertime')"); } } </code></pre> <p>Thanks for your help, any other suggestions / critique is welcome as well =)</p> <p><hr> <strong>Update:</strong> </p> <p>Spectate table entry example.<br> bid: 169<br> player: 1<br> time: 2009-10-20 21:22:54<br></p> <p>Player table entry example:<br> pid: 1<br> uid: 1<br> name: SpikeAi<br> score: 2000<br> wins: 0<br> lose: 0<br> tie: 0</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.
