有没有办法防止重复？

Question

我有这样的查询：

  $mp = NCore::db()->query("SELECT DISTINCT TOWN,NAME FROM CINEMA WHERE CITY_ID = ".$_POST['town']."");

我想要的是像这样的东西

格林维尔  .....  .....  ..... 富兰克林 ....... .......

我有下面的代码，但它写了所有的城镇名称。我想要的是我想只写一次城镇名称。有没有办法做到这一点？

<h1>Son eklenen sinema salonları</h1>
    <form action="#" method="post">
        <table border ="1">


            {foreach value=mp from=$mpbycity}

            <tr>
                <td> 


                    {$mp.TOWN}
                </td>
            </tr>
            <tr>
                <td>
                    {$mp.NAME}
                </td>
            </tr>

            {/foreach}
        </table>

</form>

我想告诉你重复的内容。有没有办法只打印一次？

Answer 1

$mp = NCore::db()->query("SELECT TOWN, NAME FROM CINEMA WHERE CITY_ID = ".$_POST['town']." GROUP BY TOWN, NAME");

Answer 2

  $mp = NCore::db()->query("SELECT TOWN,NAME FROM CINEMA WHERE CITY_ID = ".$_POST['town']." GROUP BY TOWN");

只有你想要独特的TOWN

如果是NAME和TOWN

$mp = NCore::db()->query("SELECT TOWN,NAME FROM CINEMA WHERE CITY_ID = ".$_POST['town']." GROUP BY TOWN,NAME");
