In this code

    $tj = new Model_Tagjoin();                
    $stmt = $tj->select('*')->setIntegrityCheck(false)
            ->joinInner("tags", "tags.tag_id = ".$this->_name.".tag_id",array("tag_name"))
            ->where($this->_name.".bmk_id = ?", $bmk_id)->query();                
    $r = $tj->fetchAll($stmt);

When I print_f the value of $stmt I get

SELECT `tagjoins`.*, `tags`.`tag_name` FROM `tagjoins`
INNER JOIN `tags` ON tags.tag_id = tagjoins.tag_id WHERE (tagjoins.bmk_id = '12')

which works fine if I use it directly with mysql.

Please help. Whats wrong with my code?

I don't know about using printf but as I have read it in the manual you should use the assemble() method to see your final sql query.

something like this.

$tj = new Model_Tagjoin();                
$stmt = $tj->select('*')->setIntegrityCheck(false)
        ->joinInner("tags", "tags.tag_id = ".$this->_name.".tag_id",array("tag_name"))
        ->where($this->_name.".bmk_id = ?", $bmk_id)->query()->assemble();
exit($stmt);                
$r = $tj->fetchAll($stmt);

Then try the query in phpMyAdmin and the like. As a note if this call fails you might wanna remove the ->query() part of the line.
