Php 在MySQLi Select/Like搜索中排除重复返回
在过去的几天里，我学到了很多，但如何排除重复记录让我感到困惑 使用标题搜索按钮搜索“abba” 2返回的结果 请注意，它是另一张光盘上的副本 我怎么才能展示第一次发现的呢？ 这只是一个例子：有100个重复，这是正常的。它们只是不同的光盘组。然而，Sound Choice和DK卡拉OK是不同的录音标签，不是重复的。因此，只有当光盘ID以相同代码开始时才复制-即DK088和DK056是一个复制品，但DK088和SC5101不是一个复制品，如果相同的艺术家和标题。。。或者比较品牌可能更容易 这是我目前的代码：Php 在MySQLi Select/Like搜索中排除重复返回,php,mysqli,Php,Mysqli,在过去的几天里，我学到了很多，但如何排除重复记录让我感到困惑 使用标题搜索按钮搜索“abba” 2返回的结果 请注意，它是另一张光盘上的副本 我怎么才能展示第一次发现的呢？ 这只是一个例子：有100个重复，这是正常的。它们只是不同的光盘组。然而，Sound Choice和DK卡拉OK是不同的录音标签，不是重复的。因此，只有当光盘ID以相同代码开始时才复制-即DK088和DK056是一个复制品，但DK088和SC5101不是一个复制品，如果相同的艺术家和标题。。。或者比较品牌可能更容易 这是我目

SELECT DISTINCT LEFT(discId , 2) FROM yourTable
这样你就不会得到两次DK，你会得到SC或DK，第一次出现好吧，在做了更多的研究之后。。。似乎我需要使用内部连接
