Grouping

Recommended Posts

Is there anyway of grouping the results by detention.detentiondate so that each date is only shown once?

 

 

 

$query = "SELECT detention.detentiondate, detention.pupilno, detention.reason, detention.teacherid, 
pupil.firstname, pupil.lastname FROM detention, pupil 
WHERE detention.detentiondate >= '$_SESSION[startdate]' AND detention.detentiondate <= '$_SESSION[enddate]' 
AND detention.pupilno = pupil.pupilno ORDER BY detention.detentiondate, pupil.lastname, pupil.firstname, pupil.pupilno  ";
$result = mysql_query($query);
if ($result) {
    while ($array= mysql_fetch_assoc($result)) {
       echo "<br />";
       print "$array[detentiondate]<br />";
       print "$array[pupilno]: <i>$array[firstname] $array[lastname]</i><br />";
       print "<b>Reason:</b> $array[reason]<br />";
       print "<b>Allocated By:</b> $array[teacherid]<br />"; }
       }
?>

Lets try a JOIN instead and define the GROUP BY

<?php
$query = "SELECT detention.detentiondate, detention.pupilno, detention.reason, detention.teacherid, 
pupil.firstname, pupil.lastname FROM `detention` LEFT JOIN `pupil` on (detention.pupilno = pupil.pupilno)
WHERE detention.detentiondate >= '$_SESSION[startdate]' AND detention.detentiondate <= '$_SESSION[enddate]' 
ORDER BY detention.detentiondate, pupil.lastname, pupil.firstname, pupil.pupilno 
GOUP BY detention.detentionid ";
$result = mysql_query($query) or die(mysql_error()."<br /><br />".$query);
?>

Check my spelling.

mwasif,

 

yes that is similiar to what i am looking for but it's not working even when i've changed it...have i done any thing wrong?

 

$query = "SELECT detention.detentiondate, detention.pupilno, detention.reason, detention.teacherid, 
pupil.firstname, pupil.lastname FROM detention, pupil 
WHERE detention.detentiondate >= '$_SESSION[startdate]' AND detention.detentiondate <= '$_SESSION[enddate]' 
AND detention.pupilno = pupil.pupilno ORDER BY detention.detentiondate, pupil.lastname, pupil.firstname, pupil.pupilno  ";
$result = mysql_query($query);
$current_date = "";
while($rs = mysql_fetch_array($result))
{
   if($current_date!=$rs["detentiondate"])
   {
     $current_date=$rs["detentiondate"];
       print "$array[detentiondate]<br />";
   }
   print "$array[pupilno]: <i>$array[firstname] $array[lastname]</i><br />";
   print "<b>Reason:</b> $array[reason]<br />";
   print "<b>Allocated By:</b> $array[teacherid]<br />"; 
} ?>

echo out the query it should work

it should pull all Detentions with the date range defined by those sessions all grouped under the Detention ID

 

I have used a very similar query on Events and User data

the only way it returns 0 s rows if 0 detentions exist in that date range.  The left join simply attempts to fit in any user data that falls in the User = Detention  Users 

 

Without the join if the UserData doesn't match the Events data (or users is empty) the whole query is empty

I don't have a field called detention id...but anyways.. do u mean echo it as I have been printing it before or do i need to arrange the print in any weird way?

 

thanks

You really need a primary key for the detention tables called detentionid

that is why my query is failing and if you are error reporting it as I wrote it should error

 

when I say echo it out take what is echoed out with all the php variables applied and take it into phpmyadmin and tweak it to work right.

but that's no the problem i'm having....it shows me the correct information with my original code...it just doesn't show it like this

 

 

Detention Date

 

<detentiondate>

 

             <pupilno><firstname><lastname>

            Reason: <reason>

            Issued By:<teacherid>

 

            <pupilno><firstname><lastname>

            Reason: <reason>

            Issued By:<teacherid>

 

<detentiondate>

 

            <pupilno><firstname><lastname>

            Reason: <reason>

            Issued By:<teacherid>

 

etc..

 

which is the way i need it to show
