This query works: SELECT Article.id, Article.post_time, Article.post_locked, Article.comments_locked, Article.title, IF(CHAR_LENGTH(Article.content)>2000, RPAD(LEFT(Article.content,2000),2003,’.’), Article.content) as content,

This query works:

SELECT Article.id, 
       Article.post_time, 
       Article.post_locked, 
       Article.comments_locked, Article.title,  
       IF(CHAR_LENGTH(Article.content)>2000, 
          RPAD(LEFT(Article.content,2000),2003,'.'), 
          Article.content) as content, 
       Article.tags, Category.*, 
       User.id, User.user_name, 
       Comment.comment_count 
  FROM `articles` as `Article` 
LEFT JOIN `categories` as `Category` ON `Article`.`category_id` = `Category`.`id` 
LEFT JOIN `users` as `User` ON `Article`.`user_id` = `User`.`id` 
LEFT OUTER JOIN (SELECT article_id, count(*) comment_count FROM `comments`) as `Comment` ON `Article`.id = `Comment`.article_id 
    WHERE '1'='1' 
 ORDER BY `Article`.`id` DESC

But when I loop through the resultset to assign the table name along with the field using ‘mysql_field_table’, the ‘content’ returns a table name of nothing, while all others have their correct table:

Array ( 
    [0] => Article 
    [1] => Article 
    [2] => Article 
    [3] => Article 
    [4] => Article 
    [5] => 
    [6] => Article 
    [7] => Category 
    [8] => Category 
    [9] => User 
    [10] => User 
    [11] => Comment )

using 

for ($i = 0; $i < $numOfFields; ++$i) {
   array_push($table,mysql_field_table($this->_result, $i));
   array_push($field,mysql_field_name($this->_result, $i));
}

Anyone ever try to do this? Have a solution? I want to return less data from my DB in my query. Or is it less intensive (on mysql, memory, cpu) to simply select all content and truncate the content via PHP? I thought returning less from DB would be better.

Thanks a bunch!!

Peace.

EDIT

to clear up, this is the result, you will see why it isnt what I want:

Array ( 
    [0] => Array ( 
        [Article] => Array ( 
            [id] => 8 
            [post_time] => 1278606312 
            [post_locked] => 0 
            [comments_locked] => 0 
            [title] => Article 8
            [tags] => test ) 
        [] => Array ( 
            [content] => my content for Article  ) 
        [Category] => Array ( 
            [id] => 2 
            [name] => cat2 ) 
        [User] => Array ( 
            [id] => 3 
            [user_name] => user3 ) 
        [Comment] => Array ( 
            [comment_count] => 1 ) 
    ) 
   [1] => Array ( 
        [Article] => Array ( 
            [id] => 7 
etc...

    while ($row = mysql_fetch_row($this->_result)) {
    $prev_table;
    for ($i = 0;$i < $numOfFields; ++$i) {
        if ($table[$i] == "") {
            $tempResults[$prev_table][$field[$i]] = $row[$i];
        }else {
            $tempResults[$table[$i]][$field[$i]] = $row[$i];    
        }
        $prev_table = $table[$i];
    }
}

    Oh well, mysql couldnt do what I wanted. I added the prev_table to take the one before 😉

    Thanks to everyone for the help.
