帝国CMS后台搜索提示“MySQL Illegal mix of collations for operation 'like'”解决办法

帝国CMS网站搬家时发现后台信息搜索出错，提示如下错误

Illegal mix of collations for operation 'like'
select count(*) as total from ***_ecms_crm where (title like '%高级%' or sskehu like '%高级%' or ssgs like '%高级%' or domain like '%高级%'

这是由于升级mysql5.5才会出现的错误，

只需打开 /e/admin/LisNews.php

查找：

$sr['searchallfield'].=$or.$r1[1]." like '%[!--key--]%'";

改为

$sr['searchallfield'].=$or.$r1[1]." like binary '%[!--key--]%'";

即可
