尝试在MySQL查询中使用多个WHERE命令[Not Working]

Question

如果我的查询字符串与我指定的表的列值匹配，我有一个数据库，我想要更改某个表的行值的状态..

这是我迄今为止所做的...

<?php 

$connection = mysql_connect("localhost", "creative_db", "samplepassword"); 
$db = mysql_select_db("creative_dbgogo", $connection); 

$slct = mysql_query("UPDATE zombie_links SET link_status = 'discard' WHERE link_url = '%pills%' OR link_url_title = '%pills%' OR link_title = '%pills%' OR link_title_url = '%pills%' OR link_content = '%pills%' OR link_summary = '%pills%' OR link_tags= '%pills%' ") or die(mysql_error()); 

?> 

我在做什么错？请帮忙！

Answer 1

=不采用通配符。我想你想要like：

UPDATE zombie_links 
    SET link_status = 'discard' 
    WHERE link_url like '%pills%' OR link_url_title like '%pills%' OR link_title like '%pills%' OR 
      link_title_url like '%pills%' OR link_content like '%pills%' OR 
      link_summary like '%pills%' OR link_tags like '%pills%'; 

Answer 2

试试这个

$slct = mysql_query("UPDATE zombie_links SET link_status = 'discard' WHERE link_url like '%pills%' OR link_url_title like '%pills%' OR link_title like '%pills%' OR link_title_url like '%pills%' OR link_content like '%pills%' OR link_summary like '%pills%' OR link_tags like '%pills%' ") or die(mysql_error());
