gettting an error while defining the event name on mysqlworkbench 5.5

问题

I created a stored procedure like the following:

-- --------------------------------------------------------------------------------
-- Routine DDL
-- Note: comments before and after the routine body will not be stored by the server
-- --------------------------------------------------------------------------------
DELIMITER $$

CREATE DEFINER=`MailMe`@`%` PROCEDURE `sp_archivev3`()
BEGIN

INSERT INTO 
     send.sgev3_archive(a_bi,
                        b_vc,
                        c_int,
                        d_int,
                        e_vc,
                        f_vc,
                        g_vc,
                        h_vc,
                        i_dt,
                        j_vc,
                        k_vc,
                        l_vc,
                        m_dt,
                        n_vch,
                        o_bit)
SELECT     a_bi,
           b_vc,
           c_int,
           d_int,
           e_vc,
           f_vc,
           g_vc,
           h_vc,
           i_dt,
           j_vc,
           k_vc,
           l_vc,
           m_dt,
           n_vch,
           o_bit

FROM   send.sgev3

WHERE m_dt BETWEEN  CURDATE() - INTERVAL 1 DAY AND CURDATE();


END

Now, I am trying to create an event inside the above stored procedure as follows:

---

-- Routine DDL
-- Note: comments before and after the routine body will not be stored by the server
-- --------------------------------------------------------------------------------
DELIMITER $$

CREATE DEFINER=`MailMe`@`%` PROCEDURE `sp_archivev3`()

EVENT archivescheduler

ON SCHEDULE

EVERY 10 SECOND

DO BEGIN

INSERT INTO 
     send.sgev3_archive(a_bi,
                        b_vc,
                        c_int,
                        d_int,
                        e_vc,
                        f_vc,
                        g_vc,
                        h_vc,
                        i_dt,
                        j_vc,
                        k_vc,
                        l_vc,
                        m_dt,
                        n_vch,
                        o_bit)
SELECT     a_bi,
           b_vc,
           c_int,
           d_int,
           e_vc,
           f_vc,
           g_vc,
           h_vc,
           i_dt,
           j_vc,
           k_vc,
           l_vc,
           m_dt,
           n_vch,
           o_bit

FROM   send.sgev3

WHERE m_dt BETWEEN  CURDATE() - INTERVAL 1 DAY AND CURDATE();


END

I am getting a cross symbol on the line EVENT archivescheduler in the above code. I am following the following documentation on the MySQL Website. Am I doing something wrong?

What I suspect is that since I have already created the stored procedure before and I am trying to create one, this could create some problem. Please let me know what I am doing wrong?

As small screenshot from the MySQLWORKbench of the error:

Thanks

Per documentation you can't create event inside procedure body. See this post Create an event inside a procedure - SQL.

You will have to create the procedure first and then call it from event like below

DELIMITER $$

CREATE DEFINER=`MailMe`@`%` PROCEDURE `sp_archivev3`()
BEGIN

INSERT INTO 
     send.sgev3_archive(a_bi,
                        b_vc,
                        c_int,
                        d_int,
                        e_vc,

<Rest of the code goes here>

Then create event calling the procedure

DELIMITER $$  
CREATE EVENT archivescheduler
ON SCHEDULE EVERY 10 SECOND
DO BEGIN
    CALL `sp_archivev3`();
END $$
DELIMITER ;

Another Pointer: In case your stored procedure don't fire from event; you may need to check whether GLOBAL EVENT SCHEDULER is in DISABLE state. You can turn it on using below setting

SET GLOBAL event_scheduler = ON;
