PHP PDO 微软 SQL

Question

但是我试图抓取数据库中的最后 5 个条目并在网站上回显他们的第一行，这就是我已经走了多远：

<?php

$dsn = "sqlsrv:Server=localhost;Database=blog";
$conn = new PDO($dsn, "*****", "*********");
$conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

$sql = "SELECT TOP 5 FROM blog_posts ORDER BY blogID DESC";

foreach ($conn->query($sql) as $row) {
echo $row[1];
} 
?>

错误：

致命错误：带有消息的未捕获异常“PDOException” 'SQLSTATE[42000]：[Microsoft][SQL Server Native Client 11.0][SQL 服务器]关键字“FROM”附近的语法不正确。在 C:\inetpub\wwwroot\dev\ny\includes\left-menu.php:17 堆栈跟踪：#0 C:\inetpub\wwwroot\dev\ny\includes\left-menu.php(17): PDO->query('SELECT TOP 5 FR...') #1 C:\inetpub\wwwroot\dev\ny\index.php(281): include('C:\inetpub\wwwr...') #2 {main} 抛出 C:\inetpub\wwwroot\dev\ny\includes\left-menu.php 第 17 行

Answer 1

行

$sql = "SELECT TOP 5 FROM blog_posts ORDER BY blogID DESC"; 

应该是

$sql = "SELECT TOP 5 * FROM blog_posts ORDER BY blogID DESC";
