我们正在使用以下存储过程，并且所有提到的表都使用＆＃34; Collation = utf8_general_ci＆＃34;我们仍然遇到这个错误：

错误代码：1267。操作的非法混合（utf8_general_ci，IMPLICIT）和（utf8_unicode_ci，IMPLICIT）＆＃39; =＆＃39;

存储过程是：

此SP需要更新吗？

From other answer:存储过程参数的默认排序规则是utf8_general_ci，您不能混合排序规则，这意味着数据库/表可能是unicode。

首先尝试一下：

SELECT @@collation_database;

然后查看您正在使用的实际表的CREATE语句。
