Question

I have 3 tables :

tb_wrapper              tb_doc                 tb_aut
=====================   ====================   =======================
|id|web|title|source|   |id| web | content |   |id|web|aut  | linkAut|
=====================   ====================   =======================  
|1 | A |  AA | AAA  |   |1 | A   |  AAAA   |   |1 | A | B   | C      |
=====================   ====================   |2 | A | D   | E      |
                                               =======================

I wanna get all of record data from 3 table that has same web.

here’s my code :

$query = mysql_query("
                     SELECT 
                        tb_wrapper.web,
                        tb_wrapper.title,
                        tb_wrapper.source,
                        tb_doc.web,
                        tb_doc.content,
                        tb_aut.web,
                        tb_aut.aut,
                        tb_aut.linkAut
                     FROM
                        tb_doc
                     INNER JOIN tb_wrapper ON tb_doc.web = tb_wrapper.web 
                        AND
                     INNER JOIN tb_aut ON tb_doc.web = tb_aut.web 
 ");

The error problem :
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in D:\AppServ\www\sukses\indexsummary.php on line 87.

EDIT

Then I wanna print them all :

while ($row = mysql_fetch_array($query)) {
    $source  = $row['source'];
    $title   = $row['title'];
    $content = $row['content'];
    $aut  = $row['aut'];
    $linkAut   = $row['linkAut'];
echo '<h2><a href='.$source.'> '.$title.' </a></h2>';
echo '<p><a href='.$aut_url.'> '.$aut.'  </a></p>';
}

And the result, they are printed twice. AA B and AA D. How to make them AA B D ?

Please help me. thanks in advance 🙂

$query = mysql_query("
                     SELECT 
                        tb_wrapper.web,
                        tb_wrapper.title,
                        tb_wrapper.source,
                        tb_doc.web,
                        tb_doc.content,
                        tb_aut.web,
                        tb_aut.aut,
                        tb_aut.linkAut
                     FROM
                        tb_doc
                     INNER JOIN tb_wrapper ON tb_doc.web = tb_wrapper.web
                     INNER JOIN tb_aut ON tb_doc.web = tb_aut.web 

YOu need to remove the AND between inner joins, that’s invalid syntax.
