Thanks really for ur help. As when i open my file, it opens up with SQL with some particular Server, so only i asked this. Still i find a error when i run my Select DBM perl directly : DBD::DBM::st execute failed: Cannot open .\users.lck: No such file or directory at D:/Perl/site/lib/DBD/File.pm line 574. for Statement "SELECT COUNT(*) FROM users" at H:\job\modules.pl line 13. DBI::st=HASH(0x1c10300)

following is the code i'm using

#!/usr/bin/perl -w
use strict;
use DBI;

my $dbh = DBI->connect('dbi:DBM:server=RS-ERDSG06:f_ext=.sql')
    or die "Can't connect to $DBI::errstr";

my $sql = "SELECT COUNT(*) FROM users";

my $sth = $dbh->prepare($sql)
    or die "Can't prepare statement: $DBI::errstr";

$sth->execute();

print $sth, "\n";

$dbh->disconnect;
