echo query in PHP

Is there is a way in PHP to output what query is actually being run?  I have
$getcount = mysql_query("SELECT count(RegID) as CountMe FROM Registrations WHERE CourseID = " .$row['ClassID'] . "and DateProcessed is not null");

Open in new window

which is not returning any results but it should be so I wanted to see what was actually being run.   I know how to in ASP and CF.    Thanks!

Do this:

$getcount = mysql_query("SELECT count(RegID) as CountMe FROM Registrations WHERE CourseID = " .$row['ClassID'] . "and DateProcessed is not null") or die(mysql_error() . "The query was:<br>" . $getcount;

Sorry for the typo. But I did a bad error try this:

$sql = "SELECT count(RegID) as CountMe FROM Registrations WHERE CourseID = " .$row['ClassID'] . "and DateProcessed is not null";
$getcount = mysql_query($sql) or die(mysql_error() . "The query was:<br>" . $sql);

OK - that worked only in the sense that I had an issue in the SQL (missing space) but if the query doesn't have errors - nothing outputs.    So is that not possible in PHP?

Maybe this will help.   This is what I am trying to solve.   Nothing is outputting in the table for $getcount.CountMe or $getcount2.CountMe.  What am I doing wrong?  

 
<?php
		while($row = mysql_fetch_array($getusers)){
			
			
			
		$getcount = mysql_query("SELECT count(RegID) as CountMe FROM Registrations WHERE CourseID = " .$row['ClassID'] . " and DateProcessed is not null");		
		$getcount2 = mysql_query("SELECT count(RegID) as CountMe FROM Registrations WHERE CourseID = " .$row['ClassID'] . " and DateProcessed is null");
		$finalcount = $row['SpotsAvailable'] - $getcount['CountMe'] - $getcount2['CountMe'];
			
echo "<tr><td valign='top'>";
echo "<A HREF='classes_edit.php?ClassID=" .$row['ClassID'] ."'>" .$row['ClassName'] . "</A>";
echo "</td><td valign='top'>";
echo $row['ClassLocation'];
echo "</td><td valign='top'>";
echo date("m-d-Y",strtotime($row['StartDate']));
echo "</td><td valign='top' align='center'>";
echo $row['SpotsAvailable'];
echo "</td><td valign='top' align='center'>";
echo $getcount['CountMe'];
echo "</td><td valign='top' align='center'>";
echo $getcount2['CountMe'];
echo "</td><td valign='top' align='center'>";
echo $finalcount;
echo "</td></tr>";
} 
	 ?>

You simply echo the $sql.

echo $sql;

The important thing is that you fist define your query in a variable like $sql or $query, then you can print it when and where you want.

I think with your query is the pronblem in missing quotes around the $row['ClassID'] value. In addition, I see you don't have a space before the 'AND'. Try this:

$sql = "SELECT count(RegID) as CountMe FROM Registrations WHERE CourseID = '" .$row['ClassID'] . "' and DateProcessed is not null";

OK - I think this is some sort of output error at this point.    The queries are working and they return the correct value at the direct SQL request.     Why don't I get an output.  
echo $getcount2['CountMe'];

You have to fetch $getcount:
$result = mysql_fetch_assoc($getcount);
echo $result['CountMe'];
