推荐答案

您将需要使用 DBI，并且您可能最好使用来自 (CPAN).如果您不了解 DBI，那么您需要阅读相关内容.有一本书(Programming the Perl DBI)很旧但仍然有效.

You will need to use DBI and you are probably best using the DBD::ODBC provider from (CPAN). If you don't know about DBI, then you need to read up about that. There's a book (Programming the Perl DBI) which is old but still valid.

然后是这样的:

use strict;
use warnings;
use DBI;

# Insert your DSN's name here.
my $dsn = 'DSN NAME HERE'

# Change username and password to something more meaningful
my $dbh = DBI->connect("DBI:ODBC:$dsn", 'username', 'password')

# Prepare your sql statement (perldoc DBI for much more info).
my $sth = $dbh->prepare('select id, name from mytable');

# Execute the statement.
if ($sth->execute)
{
    # This will keep returning until you run out of rows.
    while (my $row = $sth->fetchrow_hashref)
    {
        print "ID = $row->{id}, Name = $row->{name}\n";
    }
}

# Done. Close the connection.
$dbh->disconnect;
