PHP query to db

[odisey]

I am not sure if this is the right forum:

 

My question is about running a db parse query.  Using PhpMyAdmin I would run something like:

 

SELECT student.studentname, characteristics.char_desc, SUM(student_score.score) as total

FROM student_score

    INNER JOIN question  ON student_score.q_id = question.q_id

    INNER JOIN area ON question.area_id = area.area_id

    INNER JOIN characteristics ON area.char_id = characteristics.char_id

    INNER JOIN student ON student_score.student_id = student.student_id

WHERE student_score.mid_final = 'M'

    AND student_score.student_id = '7001234'

    AND student_score.year = '2006'

GROUP BY student.studentname, characteristics.char_desc

 

 

Notice I have accessed columns in two tables, student and characteristics.  Is it possable to run such a query in Php to parse a MySQL db?

 

Something like

 

    $query = "SELECT column FROM table1 AND column FROM table2, SUM SUM (student_score.score) as total

FROM student_score

    INNER JOIN question  ON student_score.q_id = question.q_id

    INNER JOIN area ON question.area_id = area.area_id

    INNER JOIN characteristics ON area.char_id = characteristics.char_id

    INNER JOIN student ON student_score.student_id = student.student_id

WHERE student_score.mid_final = 'M'

    AND student_score.student_id = '7001234'

    AND student_score.year = '2006'

GROUP BY student.studentname, characteristics.char_desc";

 

 

$result = @mysql_query($query);

   

  if ($result) {

 

 

  while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {

Yes...

[odisey]

Id is possable to get an example of the query and output?

You've done all the hard work yourself already.

 

The finishing touch (to see what you are getting) would be to do something like :

while($row ....) {

echo "<pre>";
print_r($row);
echo "</pre>";

}

Please note this is for debugging really, but it'll show you what you need to know.

Actually Barand helped me construct the tables and joins...expert.  I have the site built now...And I am adding the last page...the print results pages(s). 

 

Thank you,

I am trying this simple snippet to get a print to build from -- I get nothing...  Any ideas why?

 

 $query = "SELECT student.last_name, characteristics.char_desc

WHERE student_score.mid_final = 'M'
    AND student_score.student_id = '700900127'
    AND student_score.year = '2006'";

/*   

, SUM (student_score.score) as total
FROM student_score 

INNER JOIN question ON student_score.q_id = question.q_id
    INNER JOIN area ON question.area_id = area.area_id
    INNER JOIN characteristics ON area.char_id = characteristics.char_id
    INNER JOIN student ON student_score.student_id = student.student_id

GROUP BY student.last_name, characteristics.char_desc";    */


$result = @mysql_query($query);
          
         if ($result) {
                             echo 'result';
        
      while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
   

	/*	  	  
	   echo '<p align="left">' . $row['total'] . '</p>'; 
	   
	//  ' . $row['char_desc']'</p>'; 	
	   
	   echo '<br /><br />';     

		*/


		echo "<pre>";
print_r($row);
echo "</pre>";
		   } 
		   
	}   

 

 

 

Thank you for all your help,

Marc

Is student id and year INTs or CHARS in your DB?

 

If INTs, remove the ' '

 

AND student_score.student_id = 700900127

    AND student_score.year = 2006";

 

[odisey]

I had tried that - and again after your post...  Nothing prints...?

[odisey]

I've narrowed it down to the SELECT statement dot syntax.  Why would dot syntax execute in the WHERE statement and not the SELECT statement?

 

 

This will not execute:

 

	 $query = "SELECT student_score.description_id, student.last_name WHERE student_score.mid_final = 'M' AND student_score.student_id = 700900127 AND student_score.year = 2006 AND student.student_id = 700900127";

 

This will

 

	 $query = "SELECT description_id FROM student_score WHERE student_score.mid_final = 'M' AND student_score.student_id = 700900127 AND student_score.year = 2006";
