把mysql里所有table的varchar字段的字符集，批量换成了utf8mb4/utf8mb4_unicode_ci ，以便能保存一些表情,结果存储过程报错；
这是因为临时存储表的编码和表的编码不符；
所以在游标使用到的变量修改编码；
DECLARE qpCategory VARCHAR(32) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
即可！
Procedure execution failed 1267 - Illegal mix of collations (utf8mb4_unicode_ci,IMPLICIT) and (utf8mb4_general_ci,IMPLICIT) for operation '='
