由于函数体在Oracle中的编译错误而创建的包体

Question

我正在使用Oracle 10g Express版本。

这里是我包创建代码： -

CREATE OR REPLACE PACKAGE ticketBooking 
    AS 
     PROCEDURE bookOrder(id IN NUMBER, key IN VARCHAR2, fname IN VARCHAR2, lname IN VARCHAR2, age IN NUMBER, address IN VARCHAR2, adate IN VARCHAR2, status OUT NUMBER); 
     PROCEDURE bookTicket(id IN NUMBER, orderID IN NUMBER, mID IN NUMBER, mRow IN NUMBER, mSeat IN NUMBER, mDate IN VARCHAR2, mTime IN NUMBER, status OUT NUMBER); 
     FUNCTION maxOrderID RETURN NUMBER; 
     FUNCTION maxTransactionID RETURN NUMBER; 
    END ticketBooking; 
/

现在，这里是包体创作： -

CREATE OR REPLACE PACKAGE BODY ticketBooking 
    IS 
     PROCEDURE 
     bookOrder (id IN NUMBER, key IN VARCHAR2, fname IN VARCHAR2, lname IN VARCHAR2, age IN NUMBER, address IN VARCHAR2, adate IN VARCHAR2, status OUT NUMBER) 
     IS 
      BEGIN 
      INSERT INTO tbl_order (order_id, order_key, order_fname, order_lname, order_age, order_address, order_add_date) 
      VALUES (id, key, fname, lname, age, address, TO_DATE(adate, 'YYYY-MM-DD hh24:mi:ss')); 
      status := 1; 
      EXCEPTION 
      WHEN OTHERS THEN 
      status := 0; 
      END bookOrder; 

     PROCEDURE 
     bookTicket (id IN NUMBER, orderID IN NUMBER, mID IN NUMBER, mRow IN NUMBER, mSeat IN NUMBER, mDate IN VARCHAR2, mTime IN NUMBER, status OUT NUMBER) 
     IS 
      BEGIN 
      INSERT INTO tbl_transaction (transaction_id, order_id, movie_id, movie_row, movie_seat, movie_date, movie_time) 
      VALUES (id, orderID, mID, mRow, mSeat, mDate, mTime); 
      status := 1; 
      EXCEPTION 
      WHEN OTHERS THEN 
      status := 0; 
      END bookTicket; 

     FUNCTION 
     maxOrderID RETURN NUMBER 
     IS 
      mOID NUMBER:=0; 
      BEGIN 
      SELECT CASE WHEN MAX(order_id) > 0 THEN MAX(order_id) ELSE 0 END INTO mOID FROM tbl_order; 
      return (mOID); 
      END maxOrderID; 

     FUNCTION 
     maxTransactionID RETURN NUMBER 
     IS 
      mTID NUMBER:=0; 
      BEGIN 
      SELECT CASE WHEN MAX(transaction_id) > 0 THEN MAX(transaction_id) ELSE 0 END INTO mTID FROM tbl_transaction; 
      return (mTID); 
      END maxTransactionID; 

    END ticketBooking; 
/

我得到那个包体与编译错误创建一个错误。 我在做什么错？ 当我删除功能，那时没有警告或编译错误显示。

你缺少：

• 的函数的返回条款。添加return number
• then和end if在if小号

试试这个：如果你`显示errors`

create or replace PACKAGE BODY ticketBooking 
    IS 
     PROCEDURE 
     bookOrder (id IN NUMBER, key IN VARCHAR2, fname IN VARCHAR2, lname IN VARCHAR2, age IN NUMBER, address IN VARCHAR2, adate IN VARCHAR2, status OUT NUMBER) 
     IS 
      BEGIN 
      INSERT INTO tbl_order (order_id, order_key, order_fname, order_lname, order_age, order_address, order_add_date) 
      VALUES (id, key, fname, lname, age, address, TO_DATE(adate, 'YYYY-MM-DD hh24:mi:ss')); 
      status := 1; 
      EXCEPTION 
      WHEN OTHERS THEN 
      status := 0; 
      END bookOrder; 

     PROCEDURE 
     bookTicket (id IN NUMBER, orderID IN NUMBER, mID IN NUMBER, mRow IN NUMBER, mSeat IN NUMBER, mDate IN VARCHAR2, mTime IN NUMBER, status OUT NUMBER) 
     IS 
      BEGIN 
      INSERT INTO tbl_transaction (transaction_id, order_id, movie_id, movie_row, movie_seat, movie_date, movie_time) 
      VALUES (id, orderID, mID, mRow, mSeat, mDate, mTime); 
      status := 1; 
      EXCEPTION 
      WHEN OTHERS THEN 
      status := 0; 
      END bookTicket; 

     FUNCTION 
     maxOrderID return number 
     IS 
      mOID NUMBER:=0; 
      dReturn NUMBER:=0; 
      BEGIN 
      SELECT MAX(order_id) INTO mOID FROM tbl_order; 
      if(mOID > 0) then 
       return (mOID); 
      else 
       return (dReturn); 
       end if; 
      END maxOrderID; 

     FUNCTION 
     maxTransactionID return number 
     IS 
      mTID NUMBER:=0; 
      dReturn NUMBER:=0; 
      BEGIN 
      SELECT MAX(transaction_id) INTO mTID FROM tbl_transaction; 
      if(mTID > 0) then 
       return (mTID); 
      else 
       return (dReturn); 
       end if; 
      END maxTransactionID; 

    END ticketBooking;
