I'm new to PHP and learning more and more everyday the more I play with things.

I'm trying to write a MYSQL statement to output all results via php to a page. I have the PHP code sweet, but having some dramas trying to compose the SQL query.

Here is what I am trying to achieve..

The lines are the relationships between fields.  

Could someone gimme a hand writing an SQL statement to satisfy this?  Thanks heaps!! I have tried for a few days to do this and research, but its not getting me anywhere.

 

Thanks.

SELECT d.label, d.serial, d.exe, d.eal, d.epl, dt.Model, m.Manufacturer
FROM fac_Device AS d
JOIN fac_DeviceTemplates AS dt ON d.TemplateID = dt.TemplateID
JOIN fax_Manufacturer AS m ON dt.ManufacturerID = m.ManufacturerID
WHERE d.label = 'server1'

 

A few simple joins and you are good to go.

Thanks awjudd... but no good. any ideas???  the idea of the query is to select all and list the detail...

 

Here is the error: 

Unknown column 'd.label' in 'field list'

 

Here is the php script:

 

<html>
<body>
<?php
$username="root";
$password="";
$database="db";
mysql_connect(localhost,$username,$password);
@mysql_select_db($database) or die( "Unable to select database");
$query="SELECT `d.label` , `d.exe` , `d.eal` , `d.epl` , `dt.Model` , `m.Manufacturer` FROM  `fac_Device` AS d JOIN `fac_DeviceTemplate` AS dt ON `d.TemplateID` = dt.TemplateID JOIN `fac_Manufacturer` AS m ON `dt.ManufacturerID` = `m.ManufacturerID`";
$result=mysql_query($query)or die(mysql_error());
$num=mysql_numrows($result)or die(mysql_error());
mysql_close();
?>
<IMG SRC="http://localhost/dcim/images/logo.png"></IMG>
<table border="0" cellspacing="2" cellpadding="2">
<tr>
<h2><B>Report<BR></h2></B>
<b></B><BR><BR>
<td><B><font face="Arial, Helvetica, sans-serif">Device Name</font></B></td>
<td><B><font face="Arial, Helvetica, sans-serif">Model</font></B></td>
<td><B><font face="Arial, Helvetica, sans-serif">Manufacturer</font></B></td>
<td><B><font face="Arial, Helvetica, sans-serif">OS Version</font></B></td>
<td><B><font face="Arial, Helvetica, sans-serif">EPL</font></B></td>
<td><B><font face="Arial, Helvetica, sans-serif">EAL</font></B></td>
<td><B><font face="Arial, Helvetica, sans-serif">EXEMPT</font></B></td>
</tr>

<?php
$i=0;
while ($i < $num) {

$f1=mysql_result($result,$i,"d.label");
$f2=mysql_result($result,$i,"dt.Model");
$f3=mysql_result($result,$i,"m.manufacturer");
$f4=mysql_result($result,$i,"d.softver");
$f5=mysql_result($result,$i,"d.epl");
$f6=mysql_result($result,$i,"d.eal");
$f7=mysql_result($result,$i,"d.exe");


?>

<tr>
<td><font face="Arial, Helvetica, sans-serif"><?php echo $f1; ?></font></td>
<td><font face="Arial, Helvetica, sans-serif"><?php echo $f2; ?></font></td>
<td><font face="Arial, Helvetica, sans-serif"><?php echo $f3; ?></font></td>
<td><font face="Arial, Helvetica, sans-serif"><?php echo $f4; ?></font></td>
<td><font face="Arial, Helvetica, sans-serif"><?php echo $f5; ?></font></td>
<td><font face="Arial, Helvetica, sans-serif"><?php echo $f6; ?></font></td>
<td><font face="Arial, Helvetica, sans-serif"><?php echo $f7; ?></font></td>
</tr>

<?php
$i++;
}
?>
</body>
</html>

You copied my query wrong.  You included the aliased field in your backticks.  Because of that it is looking for `d.label` verbatim.

 

Also your script is wrong because they don't come out with the alias up front, they come out with the names as they appears.

 

 

<html>
	<body>
	<?php
		$username="root";
		$password="";
		$database="db";
		mysql_connect(localhost,$username,$password);
		@mysql_select_db($database) or die( "Unable to select database");
		$query="SELECT d.label, d.serial, d.exe, d.eal, d.epl, dt.Model, m.Manufacturer
				FROM fac_Device AS d
				JOIN fac_DeviceTemplates AS dt ON d.TemplateID = dt.TemplateID
				JOIN fax_Manufacturer AS m ON dt.ManufacturerID = m.ManufacturerID";
		$result=mysql_query($query)or die(mysql_error());
		$num=mysql_numrows($result)or die(mysql_error());
		mysql_close();
	?>
	<IMG SRC="http://localhost/dcim/images/logo.png"></IMG>
	<h2><B>Report<BR></h2></B>
	<b></B><BR><BR>
	<table border="0" cellspacing="2" cellpadding="2">
			<tr>	
				<td><B><font face="Arial, Helvetica, sans-serif">Device Name</font></B></td>
				<td><B><font face="Arial, Helvetica, sans-serif">Model</font></B></td>
				<td><B><font face="Arial, Helvetica, sans-serif">Manufacturer</font></B></td>
				<td><B><font face="Arial, Helvetica, sans-serif">OS Version</font></B></td>
				<td><B><font face="Arial, Helvetica, sans-serif">EPL</font></B></td>
				<td><B><font face="Arial, Helvetica, sans-serif">EAL</font></B></td>
				<td><B><font face="Arial, Helvetica, sans-serif">EXEMPT</font></B></td>
			</tr>

		<?php
		$i=0;
		while (($row=mysql_fetch_assoc($result))!==FALSE {

			echo '<tr>
			<td><font face="Arial, Helvetica, sans-serif">', $row['label'], '</font></td>
			<td><font face="Arial, Helvetica, sans-serif">', $row['Model'], '</font></td>
			<td><font face="Arial, Helvetica, sans-serif">', $row['Manufacturer'], '</font></td>
			<td><font face="Arial, Helvetica, sans-serif">', $row['serial'], '</font></td>
			<td><font face="Arial, Helvetica, sans-serif">', $row['exe'], '</font></td>
			<td><font face="Arial, Helvetica, sans-serif">', $row['eal'], '</font></td>
			<td><font face="Arial, Helvetica, sans-serif">', $row['epl'], '</font></td>
			</tr>';
		}
		?>
		</table>
