MSSQL Developer trying to learn MySQL

Hello masters,


I am an MSSQL developer and I want to learn MySQL. This is the sample code I usually do in my projects. I believe that if someone ported this script to MySQL, I can now start my development with ease because everything I need is there. Except for the cursors which I really hate to use :D

Thanks in advance

This is my sample MSSQL code

--------------------------------------------------

CREATE PROCEDURE pd_GetReferenceNo
@refNo NVARCHAR(10) OUTPUT
AS BEGIN
SET @refNo = 'LUCKY777'
END


---------------------------------------------------


ALTER PROCEDURE pd_InsertDetails
@name NVARCHAR(MAX)
, @vaccineID BIGINT
AS BEGIN TRY
--DECLARE @name NVARCHAR(MAX) = 'Juan Dela Cruz'
-- , @vaccineID BIGINT = 4

DECLARE @refNo NVARCHAR(10)

IF (ISNULL(@name, '') = '') BEGIN
RAISERROR('sql|Please enter your name', 11, 1)
END

DECLARE @vacinesTbl TABLE ( ID BIGINT NOT NULL IDENTITY(1,1),
Brand NVARCHAR(50) NOT NULL)
INSERT @vacinesTbl (Brand)
VALUES ('Pfizer'), ('Moderna'), ('Sinovac'), ('Sputnik V'), ('Dengvaxia')


IF NOT EXISTS ( SELECT 1
FROM @vacinesTbl
WHERE ID = @vaccineID) BEGIN
RAISERROR('sql|Invalid Vaccine', 11, 1)
END

IF (( SELECT TOP 1
Brand
FROM @vacinesTbl
WHERE ID = @vaccineID) LIKE '%Dengvaxia%') BEGIN
RAISERROR('sql|That is not a covid-19 vaccine', 11, 1)
END

EXEC pd_GetReferenceNo @refNo OUTPUT

SELECT @refNo AS RefNo
, GETUTCDATE() As DateTimeEntry
END TRY
BEGIN CATCH
DECLARE @em NVARCHAR(MAX) = ERROR_MESSAGE()
, @es INT = ERROR_SEVERITY()
, @est INT = ERROR_STATE()
RAISERROR(@em, @es, @est)
END CATCH
