由於函數體在Oracle中的編譯錯誤而創建的包體

Question

我正在使用Oracle 10g Express版本。

這裏是我包創建代碼： -

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; 
/

現在，這裏是包體創作： -

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; 
/

我得到那個包體與編譯錯誤創建一個錯誤。 我在做什麼錯？ 當我刪除功能，那時沒有警告或編譯錯誤顯示。

你缺少：

• 的函數的返回條款。添加return number
• then和end if在if小號

試試這個：如果你`顯示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;
