在Oracle 11g Express Edition中運行PL/SQL代碼 - 錯誤

Question

我試圖在Oracle 11g XE中運行以下PL/SQL代碼。就我所見，代碼沒有問題，但是，Oracle給了我錯誤 - 我不知道如何解決這些錯誤。

declare 
bookIsbn        BookTitle.Isbn%type; 
bookName        BookTitle.btName%type; 
numOfCopies        number; 

procedure getTotalLoans(
getbookIsbn            in    BookTitle.Isbn%type, 
getbookName            out    BookTitle.btName%type, 
getnumOfCopies        out    number) is 
    begin 
    SELECT BookTitle.btName, COUNT(BookCopy.isbn) 
    INTO getbookName, getnumOfCopies 
    FROM BookTitle, BookCopy, Loan 
    WHERE getBookIsbn = BookCopy.isbn 
    AND BookTitle.isbn = BookCopy.isbn 
    AND BookCopy.bcId = Loan.bcId 
    AND loan.dateback is null 
    GROUP BY BookTitle.btName, BookTitle.isbn; 
    end; 

begin 
--main block 
getTotalLoans (4,bookName,numOfCopies); 
    dbms_output.put_line('Book Name' || bookName || ' Number of copies on loan: ' || numOfCopies); 
end; 
/

而且我得到以下錯誤：

ERROR at line 2: 
ORA-06550: line 2, column 1:

任何幫助，將不勝感激。

謝謝！

當我運行它時，你給出的代碼完全適合我。但是，錯誤表明您的變量名稱和類型之間有一些額外的字符。那就是，BOOKISBNƒƒƒƒƒƒƒƒBOOKTI，所有f角色是從哪裏來的？這可能是這些錯誤處理程序正在轉換爲可打印字符的非打印字符。如果您將以下內容複製並粘貼到變量聲明並再次嘗試？

bookIsbn BookTitle.Isbn%type; 
bookName BookTitle.btName%type; 
numOfCopies number;
