非法的排序规则混合MySQL错误
在处理大量数据时出现此奇怪的错误... 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 昔 ã‹ã‚‰ ã‚ã‚‹ å ´æ‰€' 我该怎么解决?我可以以某种方式转义字符串,以免发生此错误,还是我需要以某种方式更改表编码,如果是,应该将其更改为什么?
