mysql is a relational database. therefore, the concept of a row number is
irrelevant.

Why don't you just increment a counter as you are retrieving them.
mysql_select_db("some_DB") or die("DB not available");
$query = "select some_data from some_table";
$result = mysql_query($query);
$rowcounter=0;
while ($row=mysql_fetch_array($result)){
extract($row);
$rowcounter++;
echo

Opps. I meant GROUP BY... and it looks like I don't need to include the
COUNT().
SELECT email_addr, x GROUP BY email_addr HAVING x = 1;
Is this the only way to display a listing without duplicates, or is there a
more efficient (faster) way? I don't want to DELETE the duplicates, just

SELECT DISTINCT(email_addr) FROM myTable WHERE x = 1
