Hi,

I looked through 'Categorized Questions and Answers' and also searched this site and others, and I haven't come up with an answer.

I am trying to pluck email addresses from a mysql db to send reminder letters.

My code:
#!/usr/bin/perl -w

use strict;
use CGI;
use DBI;

# Declare and initialize variables
my $host = 'hostname';
my $db = 'dbname';
my $db_user = 'dbuser';
my $db_password = 'mypassword';


my $dbh = DBI->connect("dbi:mysql:$db:$host", "$db_user", "$db_passwor
+d" or die "Couldn't connect: $DBI::errstr");

my $sth = $dbh->prepare("SELECT * FROM feRegistrants" or die "Couldn't
+ prepare SQL: $DBI::errstr");

$sth->execute or die "Couldn't execute statement: " . $sth->errstr;

my @data;

while (@data = $sth->fetchrow_array()) {

my $email = $data[5];
my $fname = $data[2];

print "Content-type:text/html\n\n";

open(MAIL, "|/usr/lib/sendmail -t -n") || die "Unable to open sendmail
+"; 

print MAIL "To: $email \nFrom: the server\n";
print MAIL "Subject: Subject\n";
print MAIL<<EOF;

Dear $fname,\n

+let us know if you are unable to attend by emailing us at *** or call
+ing us at ***.

EOF

close(MAIL);

}

$dbh->disconnect();

The error messages I get are:
Useless use of string in void context at ./email2.cgi line 16.
Useless use of string in void context at ./email2.cgi line 16.
Can't connect(ch@ngeme), no database driver specified and DBI_DSN env var not set at ./email2.cgi line 16

Any suggestions?
