一开始是怀疑当前接口调用的sql脚本里面是不是包含了函数（存储过程之类的），仔细检查后发现当前接口的sql里面没有类似的调用呀.....

然后才发现是数据库用户名变更，在定义的函数里面没有变更对应的数据库用户名。

eg：原来数据库中的用户是 useryyy ,定义函数的时候也是用的 useryyy ;后来数据库变更，将用户useryyy改为了userxxx,但是函数的定义用户没有更改，还是原来的用户 useryyy。

解决方案：

使用root用户登录数据库，将对应的函数定义者更改为新的用户即可。（useryyy --> userxxx）

参考下图：（将下图的定义者更改为当前登录数据库（需要从数据库中查询数据的用户）的用户即可）
