oracle update stored procedure with user defined exception

Question

I am trying to create this stored procedure which should take customer no and email address as input. Then update the email address for that customer. if new email address is same as old then exception should be raised.

CREATE OR REPLACE PROCEDURE UpdateEmail
(CUSTOMERID IN CUSTOMER.CUSTOMERNO%TYPE, 
 N_EMAIL IN CUSTOMER.EMAIL%TYPE)

IS
DECLARE 
  e_same EXCEPTION;
  V_ROWCOUNT NUMBER;

BEGIN
SELECT COUNT(EMAIL)
INTO V_ROWCOUNT
FROM CUSTOMER@FIT5148B
WHERE CUSTOMER.EMAIL = N_EMAIL
AND CUSTOMER.CUSTOMERNO = CUSTOMERID;

IF V_ROWCOUNT > 0

THEN RAISE e_same;
ELSE 
UPDATE CUSTOMER
SET EMAIL = N_EMAIL
WHERE CUSTOMER.CUSTOMERNO = CUSTOMERID;
END IF;

EXCEPTION
 WHEN e_same THEN dbms_output.put_line ('email address exist');
END;
/

But it is throwing error. Not sure if I am doing it right. I am using the latest Oracle SQL Developer.

Answer 1

Remove DECLARE .

You should not use Declare in a Procedure. If you are writing a PLSQL block then only you should use Declare . Not in an actual Procedure body.
