如何在Perl的DBI中使用绑定查询选择空行？

use strict;
use warnings;
use DBI;

# 创建数据库连接
my $dsn = "DBI:mysql:database=test;host=localhost";
my $username = "username";
my $password = "password";
my $dbh = DBI->connect($dsn, $username, $password, { RaiseError => 1 });

# 准备SQL查询语句
my $sql = "SELECT * FROM users WHERE name = ?";
my $sth = $dbh->prepare($sql);

# 使用绑定查询的方式执行SQL查询语句
$sth->execute("");

# 处理查询结果
while (my @row = $sth->fetchrow_array()) {
    print join(", ", @row), "\n";
}

# 关闭数据库连接
$sth->finish();
$dbh->disconnect();
