检查导入sql，发现这个function是在root用户下面的，所以将已定义的function全部删除重建，全部在cxcs这个用户下面，结果发现还是不行，错误依旧。
后来查阅资料时，看到有博主碰到过用户没有给execute权限的情况：/lwei_998/article/details/44177741
想起来好像自己也没有给用户赋予执行权限，使用show命令查看一下show grants for 'cxcs'@'localhost'
果然是这个原因，用户cxcs只有“select,insert,update,delete,create,drop,alter”这几个权限，赶紧grant一个execute给用户cxcsgrant execute on hzcx.* to 'cxcs'@'localhost'
问题解决！
