Got a doozy here. Part of the web reporting that Mgmt wants includes a running list of subscribers to our newsletter.

Background - I'm running Linux/Apache with FreeTDS/DBD::Sybase connecting to a Win2K box with SQL Server 7.0.

Every time someone subscribes they put in their address (specifically the State they live in) and the DB includes the date/time they subscribed.

Sample record:
Col 1 - John Smith Col 2 - NY Col 3 - 02/06/2003

I print to screen the top ten states and the count of subscribers in descending order.

Example
             Jan   Feb   Mar
New York     115     0     0
Florida       34     0     0
Georgia       28     0     0

Here's how I do it.
     my $sth = $dbh->prepare("SELECT DISTINCT state, COUNT(*) FROM con
+tacts WHERE state != '' AND identifier BETWEEN '2003-01-01' AND '2003
+-02-01' GROUP BY state ORDER BY 2 DESC"); 
     $sth->execute() or die $sth->errstr; 
     my $rows = 0;
     while (my @result = $sth->fetchrow_array()) {
     last if $rows++ >= 10;
     print qq(<tr><td><p style="margin-left: 10"><font size="2" face="
+Arial">$result[0]</font></td><td><div align="right"><font size="2" fa
+ce="Arial">&nbsp;</font></div></td><td><font size="2" face="Arial"><d
+iv align="right">$result[1]</div></font></td><td><div align="right"><
+font size="2" face="Arial">0</font></div></td><tr>\n);    
     }
     $sth->finish();

But how can I do this for the following months?
Here's what I need it to look like.

            Jan    Feb    Mar
New York    115    100      0
Georgia      28     45      0
Florida      34     10      0

I need the order to be listed by the current month and still show what happened the previous months.

Can anyone help point me in the right direction?
