我已经编写了一个以 CUSTOMER_ID 作为输入的过程。然后该过程从表 CUSTOMERS 中删除相应的客户。

CREATE OR REPlACE PROCEDURE DELETE_CUSTOMER 
(CUSTOMER_ID NUMBER) AS 
TOT_CUSTOMERS NUMBER;
BEGIN
    DELETE FROM CUSTOMERS
    WHERE CUSTOMERS.CUSTOMER_ID = DELETE_CUSTOMER.CUSTOMER_ID;
    TOT_CUSTOMERS := TOT_CUSTOMERS - 1;
    END;
/

我必须执行删除 ID 为 1 的客户的过程。

EXECUTE DELETE_CUSTOMER(01);

当我这样做时，我收到一个错误

Error starting at line : 120 in command -
BEGIN DELETE_CUSTOMER(01); END;
Error report -
