c＃mysql存储过程插入返回值

Question

I have this MySQL Stored Procedure which I use to Insert a record into the database. If I use ExecuteScalar() or ExecuteNonQuery() command in C# to call this procedure, it is returning null for a successful insert. As per my knowledge the number of rows affected is inserted, which is not 0 in my case. Here's the link

How do I return the number of inserted records

DELIMITER $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `Contact_AddNew`(codeName varchar(50), fName varchar(50), lName varchar(50), contact varchar(50))
BEGIN
    SET @codeName = codeName;
    SET @fName = fName;
    SET @lName = lName;
    SET @contact = contact;
    SET @query = 'INSERT INTO Contacts (contactName, firstname, lastname, phone) VALUES (?,?,?,?)';
    PREPARE stmt FROM @query;
    EXECUTE stmt USING @codeName, @fName, @lName, @contact;
    DEALLOCATE PREPARE stmt;
END

Answering my own question here..

A simple SELECT ROW_COUNT() will do..
