python 执行数据迁移报错
mysql :
1267, "Illegal mix of collations (latin1_swedish_ci,IMPLICIT
解决方法：
替换TABLE 后面的表名为你自己的表名，mysql 黑窗口执行。
以下是我的表名，仅作参考
ALTER TABLE book CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
ALTER TABLE book_big_category CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
