registerWithCredentials（）存储过程

Question

我已经在MysQL中为Wordpress数据库创建了一个存储过程。这一程序的目的是为了注册一个新用户到WordPress数据库使用凭证（user_login，user_pass，user_nicename，user_email，和displayname。）这个程序的SQL语法是好的，但是当我打电话的过程我不能得到响应任何东西，这东西会告诉如果新用户已添加到数据库中。我不知道问题出在哪里，因为在调用该过程后，当我登录数据库时，我看不到任何更改。

我认为您需要在代码末尾进行选择，以便可以从存储过程中输出某些内容。如果我像你一样，我将输出新注册用户的数据。以下是程序，希望对您有所帮助：
