Error Code: 1267. Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (utf8_general_ci,IMPLICIT

Mysql查询报错

Error Code: 1267. Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (utf8_general_ci,IMPLICIT) for operation '=' 0.001 sec

提示两个表的编码不一致，需要进行转换

将比较等式一边进行字符串转换，如改为“CONVERT(table-colum USING utf8) COLLATE utf8_unicode_ci”
