排序规则的非法混合 MySQL 错误
我在处理大量数据时遇到这个奇怪的错误...
I'm getting this strange error while processing a large number of data...
Error Number: 1267
Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '='
SELECT COUNT(*) as num from keywords WHERE campaignId='12' AND LCASE(keyword)='hello again æ˜" ã‹ã‚‰ ã‚ã‚‹ å ´æ‰€'
我该怎么做才能解决这个问题?我可以以某种方式转义字符串以便不会发生此错误，或者我是否需要以某种方式更改我的表编码，如果是这样，我应该将其更改为什么?
What can I do to resolve this? Can I escape the string somehow so this error wouldn't occur, or do I need to change my table encoding somehow, and if so, what should I change it to?
推荐答案
SET collation_connection = 'utf8_general_ci';
然后用于您的数据库
ALTER DATABASE your_database_name CHARACTER SET utf8 COLLATE utf8_general_ci;
ALTER TABLE your_table_name CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
MySQL 有时会无缘无故地偷偷溜进来.
MySQL sneaks swedish in there sometimes for no sensible reason.
