Answer 1

尝试使用触发器。

   CREATE TABLE customer_master(
      cust_id NUMBER(6)  PRIMARY KEY, 
      cust_password VARCHAR2(10),
      cust_fname VARCHAR2(30),
      cust_lname VARCHAR2(30),
      cust_gender VARCHAR2(8),
      cust_dob DATE,
      cust_email VARCHAR2(30),
      cust_mobile NUMBER(10),
      cust_add VARCHAR2(100),
      newsletter VARCHAR2(5) CHECK (newsletter IN('yes','no')),
      mob_service VARCHAR2(5) CHECK (mob_service IN('yes','no'))
    );

    CREATE OR REPLACE TRIGGER  INS_customer_master
    BEFORE INSERT ON customer_master
    FOR EACH ROW
    DECLARE
        i_LAST NUMBER;
    BEGIN
        SELECT CUSTOMER_SEQ.NEXTVAL INTO i_LAST FROM Dual;
        :NEW.cust_id := i_LAST;
    END;
    /

使用序列时缺少右括号
