mysql - php创建存储过程的问题

Question

我用mysqli的面向过程方法创建存储过程

<?php
$con = mysqli_connect('localhost', 'root', 'password', 'test');
if(mysqli_connect_errno($con)){
    return mysqli_connect_error;
}
$sql = "
CREATE PROCEDURE pro1(IN title varchar)
BEGIN
DELETE FROM user WHERE username=title;
END;
";
mysqli_query($con, $sql);
mysqli_close($con);

存储过程并没有被创建，请问这是怎么回事？

我把sql语句复制到phpmyadmin里面一切正常·
