DO 
BEGIN 
    DELETE 
    FROM bariq_DB.invoice 
    where timestampdiff(MONTH,created_at,NOW()) &gt; 2 and payment_status = 2; 
    delete from bariq_DB.order_details

But the events is not deleting any thing that matches the conditions, what Im missing here?
Any help will be much appreciated
You have to make the event stay put using ON COMPLETION PRESERVE
DELIMITER //
DROP EVENT IF EXISTS daily_delete //
CREATE EVENT 
IF NOT EXISTS daily_delete 
ON SCHEDULE EVERY 1 DAY STARTS (CURDATE() + INTERVAL 1 DAY + INTERVAL 0 SECOND)
ON COMPLETION PRESERVE
DO 
BEGIN 
    DELETE 
    FROM bariq_DB.invoice 
    where timestampdiff(MONTH,created_at,NOW()) &gt; 2 and payment_status = 2; 
    delete from bariq_DB.order_details 
    where timestampdiff(MONTH,created_at,NOW()) &gt; 2 and payment_status = 3; 
END;//
DELIMITER ;

See my examples in the following posts

Jun 08, 2015 : Use event schedule and stored procedure to automatically average every hour MySQL
Jun 08, 2015 : Choosing what table fields to partition on
Sep 19, 2014 : Creating Event that execute at end of each month
Aug 28, 2014 : Adding time to an event that runs on a weekly basis

This will kickoff the event starting midnight tomorrow
You never start an event in the past. You must always start an event in the future.
