Convert sql plus to mysql

[noahjonesnoah]

Im trying to convert a procedure from using sql plus to mysql but cannot get it to work.

SQL Plus:

CREATE OR REPLACE PROCEDURE PRC_CUS_BALANCE_UPDATE (W_IN IN NUMBER) AS
W_CUS NUMBER := 0;
W_TOT NUMBER := 0;
BEGIN
    -- GET THE CUS_CODE
    SELECT CUS_CODE INTO W_CUS 
    FROM INVOICE
    WHERE INVOICE.INV_NUMBER = W_IN;

    -- UPDATES CUSTOMER IF W_CUS > 0
    IF W_CUS > 0 THEN
        UPDATE CUSTOMER
        SET CUS_BALANCE = CUS_BALANCE + 
                    (SELECT INV_TOTAL FROM INVOICE WHERE INV_NUMBER = W_IN)
        WHERE CUS_CODE = W_CUS;
    END IF;
END;

mySQL:

DELIMITER $$

CREATE PROCEDURE prc_cus_balance_update (IN W_IN NUMBER) AS
W_CUS NUMBER = 0;
W_TOT NUMBER = 0;
BEGIN
    -- GET CUS_CODE
    SELECT CUS_CODE INTO W_CUS 
    FROM INVOICE
    WHERE INVOICE.INV_NUMBER = W_IN;

    -- UPDATES CUSTOMER IF W_CUS > 0
    IF W_CUS > 0 THEN
        UPDATE CUSTOMER
        SET CUS_BALANCE = CUS_BALANCE + 
                    (SELECT INV_TOTAL FROM INVOICE WHERE INV_NUMBER = W_IN)
        WHERE CUS_CODE = W_CUS;
    END IF;
END $$

DELIMITER ;

I keep getting an error on the line "CREATE PROCEDURE prc_cus_balance_update (IN W_IN DOUBLE) AS" and get an syntax error over AS.

Any help is greatly appreciated!

use declare work after begin

CREATE PROCEDURE sp1 (x VARCHAR(5))
  BEGIN
    DECLARE xname VARCHAR(5) DEFAULT 'bob';
    DECLARE newname VARCHAR(5);
    DECLARE xid INT;

    SELECT xname,id INTO newname,xid 
      FROM table1 WHERE xname = xname;
    SELECT newname;
  END;
