我的PHP页面应该显示一个MSSQL表的每行4行。显示四行后，接下来的四行将显示在新创建的页面上，上一页上有链接以授予对它的访问权限。当然，这段代码已经与MySQL一起进行了一些编辑。我想错误来自$ sql代码，但我不确切知道导致它的原因。当我在网站上运行我的PHP页面时，我似乎得到了错误
Warning: mssql_query() [function.mssql-query]: message: Incorrect syntax near 'LIMIT'. (severity 15) in D:\Hosting\4502990\html\sales\usedunits.php on line 8
Warning: mssql_query() [function.mssql-query]: Query failed in D:\Hosting\4502990\html\sales\usedunits.php on line 8
Incorrect syntax near 'LIMIT'.
这是我的完整PHP页面代码：
<?php
if (isset($_GET["page"])) { $page = $_GET["page"]; } else { $page=1; };
// connect to db
$connection = mssql_connect('gbam','GBaer','dsa!');
mssql_select_db('asdr',$connection);
$start_from = ($page-1) * 4;
$sql = "SELECT * FROM used_trailers1 ORDER BY orderid ASC LIMIT '$start_from',4";
$rs_result = mssql_query ($sql, $connection);
echo mssql_get_last_message( $connection );
?>

我已将代码更改为$sql = "SELECT TOP $start_from * FROM used_trailers1 ORDER BY orderid";。我知道这不是我想要的，因为在第1页它显示了0行。在第二页上，它显示了4行，在第3页上显示了8行。有没有办法可以在那里添加4的最大限制？
感谢您的帮助。感谢所有帮助。

只是为了帮助将要登陆此页面的人，它应该使用＆＃34; TOP ＆＃34;限制mssql_query的结果。
例如：
mssql_query( "select top 10 * from tablename" );

LIMIT子句接受数字。由于您使用单引号包围$start_from，因此它被解释为varchar文字，LIMIT语法不允许这样做。放下它们就可以了：
$sql = "SELECT * FROM used_trailers1 ORDER BY orderid ASC LIMIT $start_from, 4";

LIMIT子句必须以整数附加到varchar。尝试使用任何静态整数值而不是$ start from。
