the problem is not the code. the problem is at sql statement

coz i have made some tests and found the problem is in sql statement

this statement works

my $data = $DBH->prepare("SELECT SND.userid, SND.fname, SND.lname
FROM msg as M
JOIN users as SND 
  ON SND.userid = M.msg_from
WHERE M.msg_to = ? 
  AND M.received iS NULL");

<p>but my problem and question was after adding some column to table m
+sg and printing them out. i get error that tells me cant find such da
+ta from db according to my script. that means cant locate any data in
+ db </p>
<p>my problem is here wen i include other columns to be selected. the 
+statement dies and cant print anything just getting error nothing to 
+print from db</p>
<code>
my $data = $DBH->prepare("SELECT SND.userid, SND.fname, SND.lname, SND
+.city, SND.age, SND.city 
FROM msg as M
JOIN users as SND 
  ON SND.userid = M.msg_from
WHERE M.msg_to = ? 
  AND M.received iS NULL");
