sql-server-2005 - 从 Perl 连接到 SQL Server 2005 并执行 SELECT

Question

如何从 Perl 脚本在 SQL Server 2005 上执行 SELECT？

Answer 1

您将需要使用 DBI，并且最好使用 ( CPAN ) 中的 DBD::ODBC 提供程序。如果您不了解 DBI，那么您需要阅读相关内容。有本书( Programming the Perl DBI )很旧但仍然有效。

然后类似下面的内容:

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;
