Question

假设我有以下代码：

SELECT * FROM table where company LIKE '%Auto%'

我收到更多结果，我希望有一个按字母顺序对结果进行排序的选项，假设用户想要对以“C”开头的搜索结果进行排序！

最诚挚的问候，

Answer 1

好吧，你似乎在谈论两件不同的事情。如果您对排序感兴趣，则需要使用ORDER BY子句：

SELECT * FROM table ORDER BY name

如果您想按字母“C”开头的项目过滤结果，那么您可能希望使用该字母添加另一个LIKE子句：

SELECT * FROM table where company LIKE '%Auto%' AND name LIKE 'C%'

此外，您会注意到名称过滤器在查询后只有%。这是“以...开头”

的语法

Answer 2

使用ORDER BY子句：

SELECT *
FROM table
where company LIKE '%Auto%'
order by company

Answer 3

添加ORDER BY company，假设您要按公司价值排序。

试一试.....这是我的工作实例 排序记录字典顺序ABCD .... Z当我点击一封信然后其显示所有名称以A字母开头，然后点击C信然后它的节目所有名字都以C字母开头

     <?php
 $host = "localhost";  
 $user = "root";
 $pw = "";
 $database = "test";

 $con = mysql_connect($host,$user,$pw)
   or die("Cannot connect to mySQL.");

 mysql_select_db($database,$con)
   or die("Cannot connect to database.");




$errormsg= "No Record Found...!";


$alpha="%";
if (isset($_REQUEST['alpha'])) {
$alpha = $_REQUEST['alpha']."%";
}
$q1 = mysql_query("select * from registration where firstname like '$alpha%' " );
