Trying to convert SQL Server to MySql for class - mysql

Question

I am trying to convert code given by teacher that is in SQL Server to MySQL. It ultimately should allow me to input information to the table that was made. This is a for a guest book assignment. Unfortunately I cannot find the correct syntax as I have never worked with SQL programming in general before.
I have tried using brackets,semi colons and commas for the information as well as adding a delimeter which eliminated the "Unrecognized statement type (near PROCEDURE)" error messages that had initially been in the programming as well.
Teachers code:
CREATE PROCEDURE spInsertGuestbookEntry
#GuestBookName varchar(200),
#GuestBookEntry ntext,
#GuestbookEmail varchar(200),
#GuestBookIP varchar(20)
AS
BEGIN
SET NOCOUNT ON;
INSERT INTO Guestbook
(GuestbookName, GuestBookEntry, GuestbookEmail, GuestBookIP, GuestBookDate)
VALUES
(#GuestbookName, #GuestBookEntry, #GuestbookEmail, #GuestBookIP, GetDate())
END
GO
My modifications:
DELIMITER $$
CREATE PROCEDURE spInsertGuestbookEntry
#GuestBookName varchar(200)
#GuestBookEntry text
#GuestbookEmail varchar(200)
#GuestBookIP varchar(20)
#GuestBookDate date
AS
BEGIN
SET NOCOUNT ON;
INSERT INTO Guestbook
(GuestbookName, GuestBookEntry, GuestbookEmail, GuestBookIP, GuestBookDate)
VALUES
(#GuestbookName, #GuestBookEntry, #GuestbookEmail, #GuestBookIP, #GuestBookDate)
END
GO
The error messages that I got was "Unrecognized data type. (near))" That error message is by the #GuestBookName varchar(200)

Answer 1

DELIMITER $$
CREATE PROCEDURE `spInsertGuestbookEntry`(
IN `str_GuestBookName` VARCHAR(200),
IN `str_GuestBookEntry` TEXT,
IN `str_GuestbookEmail` VARCHAR(200),
IN `str_GuestBookIP` VARCHAR(20)
)
LANGUAGE SQL
NOT DETERMINISTIC
CONTAINS SQL
SQL SECURITY DEFINER
COMMENT ''
BEGIN
INSERT INTO Guestbook
(GuestbookName, GuestBookEntry, GuestbookEmail, GuestBookIP, GuestBookDate)
VALUES
(str_GuestBookName, str_GuestBookEntry, str_GuestbookEmail, str_GuestBookIP, CURRENT_DATE());
END

Key points to consider:
Distinguish between table column_name and procedure input parameter.
# is used to create user-defined variables in MySQL and you should be using this if your parameter is of type OUT/INOUT while calling procedure.
In procedure/function creation, simple variable names are used, not with # symbol otherwise while using these parameters, MySQL will look for some variable with this name, not the input parameter.
