I am creating a simple SQL query in PHP – and for some reason, even when DISTINCT is used, it shows twice like this:

BC
BC
OH
OH
TX
TX

Here is my code:

<?php
$sql = "SELECT DISTINCT `title`,`extra_fields_search` FROM `blahblah_items` WHERE catid=336 ORDER BY `blahblah_items`.`extra_fields_search` ASC ";
$partnerlisting= mysql_query($sql) or die(mysql_error());
while($row = mysql_fetch_assoc($partnerlisting))
foreach($row as $cname => $cvalue){
echo '<li>'.substr($row[extra_fields_search], 0, 2).'</li><br>';
}
;

?>

How can I make it so it prints out only one of each?

    SELECT 
    `title`,
    `extra_fields_search` 
FROM 
    `blahblah_items` 
WHERE 
    catid=336 
GROUP BY 
    SUBSTRING(extra_fields_search,1,2) # here. group by first two characters of extra_fields_search
    # or just "GROUP BY extra_fields_search", depends what you need
ORDER BY 
    `blahblah_items`.`extra_fields_search` ASC

    SELECT DISTINCT a,b FROM table works in same way as SELECT a,b FROM table GROUP BY a,b

    Please follow documentation:
