need advice urgent

[mohankrishna919]

I am new to perl
but after spending late nights for some days , i was able to generate code for database backup. the code will ask you enter servername , enter database name if i enter it will take backup
suppose my code is in backup.pl
now the thing is i need to get database backup by entering like this perl backup.pl -i servername -d databasename
if i hit enter it should take backup of given server name and database name.

My code:

use strict;
use Win32::SqlServer qw(SCALAR);

print "Please enter DB name:\n";
my $name = <STDIN>;
chomp($name);
# Log in to server .

my $sqlsrv = Win32::SqlServer::sql_init('localhost', 'geff', 'gentle', 'Northwind');
# Our SQL statement.

my $stmnt = <<SQLEND;
BACKUP database "$name" TO DISK = N'c:\\bak\\master.dmp'
SQLEND

# Run query.
my $result = $sqlsrv->sql($stmnt, SCALAR);

# Print results.
foreach my $name (@$result) {
print "$name\n";
}

You can run a command like this

perl myscript.pl username servername

simply by adding lines like these into your code:

$parameter1=$ARGV[0];
$parameter2=$ARGV[1];

Further parameters are just $ARGV[2], $ARGV[3] etc.

If I want something fancier I use

use Getopt::Long;
#get parameters
GetOptions("version=s" =>\$param{version},"fast=s" =>\$param{fast});
if(! $param{version})
{
    print "\nYou must specify the version attribute of the project e.g. -version 6.4.2_215\n";
    exit 1;
}
if(! $param{fast})
{
    print "\nYou must specify whether or not fast mode is to be used i.e. -fast yes|no\n";
    exit 1;
}
my $output_name=$param{version};
my $fast=$param{fast};
print "$output_name\n$fast\n"

This enables you to use a command like:

perl myscript.pl -fast yes -version 6.5.2_675
