Question

I have never tried this but want to echo data from several different tables and order them by their timestamp. The code I have comes up with a booleon and i dont know why.

 <?php
$result = mysql_query("SELECT * FROM artists ORDER BY timestamp DESC
UNION
SELECT * FROM news ORDER BY timestamp DESC
UNION
SELECT * FROM tracks ORDER BY timestamp DESC
UNION
SELECT * FROM gigs ORDER BY timestamp DESC
UNION
SELECT * FROM feature ORDER BY timestamp DESC");

while($row = mysql_fetch_array($result)){echo'News: <a      href="index.html">'.$row['name'].$row['title'].$row['trackname'].$row['gigname'].'</a><br>'     ;}

?>

Answer 1

Assuming your tables fall within the constraints of the UNION function..

Try:

SELECT * FROM 
    (SELECT * FROM artists ORDER BY timestamp DESC
    UNION
    SELECT * FROM news ORDER BY timestamp DESC
    UNION
    SELECT * FROM tracks ORDER BY timestamp DESC
    UNION
    SELECT * FROM gigs ORDER BY timestamp DESC
    UNION
    SELECT * FROM feature ORDER BY timestamp DESC) as temp
ORDER by timestamp DESC;
