在MYSQL计数查询中获取额外的数据

Question

Hi all i've had help from bluefleet (BF) with a mysql query which i've now put in a php file, the query works fine but i find i need to get extra data as well as the count, so what i need is when a match is found i need to look up the username in table tview3.

Whichever table the ip match is found there will be a column called UID, in the table tview3 there will also be a column called USERNAME, what i'd like to do is get the username(s) for the matches and then use them in a text file.

I have to state i'm a complete newbie at this, all help is appreciated

$myquery= "select sum(total)
from
(
    SELECT count(*) as total
    FROM " .TABLE_PREFIX."tview v
    where v.ipaddress = '$ips'
    union all
    SELECT count(*) as total
    FROM " .TABLE_PREFIX."tview2 v1
    where v1.ipaddress = '$ips'
    union all
    SELECT count(*) as total
    FROM " .TABLE_PREFIX."tview3 v3
    where v3.ipaddress = '$ips'
) src";

 $result = mysql_query($myquery);
    $rowCount = mysql_num_rows($result);
    If($rowCount !=0){
       echo "NOT EMPTY";
    }else{
      echo "EMPTY";
    }
   mysql_free_result($result);

$UAM = strtoupper($_SERVER['HTTP_USER_AGENT']);
$ips = strtoupper($_SERVER['REMOTE_ADDR']);
$fp = fopen("logtext.txt", "a");
$DateOfRequest = date('m-d-Y H:i:s');

fwrite($fp, "$DateOfRequest . \nMatched Member: . $username . \nWith User Agent:  . $UAM . \n\nIP: . $ips . \n\n");

So i'd like to populate a variable $username with the username(s) where the matches were found.

Answer 1

Change:

SELECT count(*) as total

to

 SELECT count(*) as total, username

Then you could do something like:

$row = mysql_fetch_array($query);
$username = $row['username'];

Hope that helps. Also check out this question for a bit more detail: How do I find the most common result in a column in my MySQL table
