Trouble using LEFTJOIN when table 2 contains 60,000+ records!

[Antivirus]

I am having BIG problems with pageload times when executing the following query:

PHP Code:

$queryvenues = $db->query_read("
    SELECT " . TABLE_PREFIX . "erc_venue.*, " . TABLE_PREFIX . "dma.* 
    FROM " . TABLE_PREFIX . "erc_venue
    LEFT JOIN " . TABLE_PREFIX . "dma ON " . TABLE_PREFIX . "dma.zipcode = " . TABLE_PREFIX . "erc_venue.venuezipcode
    ORDER BY " . TABLE_PREFIX . "erc_venue.venuetitle
"); 


Just to give you all an idea of my db, the erc_venue table contains more than 1,000 records and the dma table contains more than 60,000 records...

FYI, the function i have created to display the results is as follows:

PHP Code:

function print_venue_row($venue) 
{
        if ($venue['venuecountry'] = 'USA' AND $venue['venuezipcode'] != 0)
        { 
            $venuedma = $venue['dmaname_clean'] . " (" . $venue['rank'] . ")";
        } 
        else 
        { 
            $venuedma = ''; 
        } 

    print_cells_row(array(
        "<a href=\"erc_editvenue.php?venueid=".$venue['venueid']."\">".$venue['venuetitle']."</a>",
        $venue['venuecitystate'],
                $venuedma,
        $venue['venueid'],
        "<a href=\"".$venue['venueurl']."\" target=\"_blank\"><img src=\"../images/buttons/ip.gif\" alt=\"".$venue['venueurl']."\" border=\"0\" /></a>",
        "<input type=\"radio\" name=\"idforaction\" value=\"".$venue['venueid']."\">"
    ));
} 


When executing this query, it can take as long as 122 seconds to load the page! Is there any way I could re-write the query (or the function print_venue_row) more efficiently to help load the page more quickly?

Thanks in advance for your assistance
