它取决于值集的数量吗？它是否依赖于INSERT语句中的字节数？

我初学java,我需要像这样:

String2GzipFile (String file_content, String file_name)
String2GzipFile("Lorem ipsum dolor sit amet, consectetur adipiscing elit.", "lorem.txt.gz")

我无法弄清楚如何做到这一点.

有一栏 url(nvarchar(200), not null)

<?php
//
$pdo = new PDO('odbc:mssql', 'xxx', 'yyy');
$pdo->setAttribute(PDO::ATTR_PERSISTENT, false);
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);

// plain sql query: WORKS FINE!
$sth = $pdo->prepare("SELECT COUNT(*) FROM pagina WHERE url = '/webito'");
$sth->execute();

// using bindValue: ERROR!
$sth = $pdo->prepare("SELECT COUNT(*) FROM pagina WHERE url = :unique_value");
$sth->execute(array('unique_value' => '/webito'));

返回错误:
