registerWithCredentials() Stored Procedure

Question

I have created a stored procedure in MysQL for my Wordpress Database. The purpose of this procedure is to register a new user into wordpress database using credentials(user_login,user_pass,user_nicename,user_email,and displayname.) The sql syntax of this procedure is ok, but when i call the procedure i cant get anything in response, something that will tell if the new user is added into database. I dont know what the problem is because when i check into database after calling the procedure, i see no changes made.

I think you need to make a select in the end of your code so you can output something from your stored procedure. In your case I would output the data of the new registered user. For example:
