<?php
$strNewsQuery = '
    SELECT TOP 15
        N.[title],
        C.[title] AS category,
        C.[icon] AS icon,
        N.[datetime],
        N.[forenlink],
        N.[text]
    FROM [' . $_CONFIG['db_databases']['web'] . '].[dbo].[web_news] AS N
        LEFT JOIN [' . $_CONFIG['db_databases']['web'] . '].[dbo].[web_newscategories] AS C ON C.ncatid = N.category
    ORDER BY nid DESC
';
$dbNewsQuery = @odbc_exec($odbc_connect, $strNewsQuery);

if(@odbc_num_rows($dbNewsQuery) > 0) {
    while($mixedNewsEntry = @odbc_fetch_array($dbNewsQuery)) {
        echo '
        <div class="media-box">

如何将这个sql限制为5我试过＆＃34;限制0,5＆＃34; ＆＃34; ORDER BY nid DESC＆＃34;结束时的方法不起作用并尝试其他方法，如java语法

Answer 1

将更改为<html> <head> <script type="text/javascript"> var i,j; for(i=1; i <= 5; i++) { for(j=1; j<=i; j++) { document.write('*'); } document.write('<br />'); } </script> </head> <body> </body> </html>

Answer 2

用于选择5行的SQL是：SELECT * FROM TABLE1 ORDER BY id DESC LIMIT 5;

限制sql php中的数据
