将PL / SQL代码运行到Oracle 11g Express Edition中 - 错误

Question

我正在尝试将以下PL / SQL代码运行到Oracle 11g XE中。据我所知，代码没有任何问题，但Oracle会给我错误 - 我不知道如何解决。

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;
/

我收到以下错误：

任何帮助都将不胜感激。

谢谢！

当我运行它时，你给出的代码对我来说非常合适。但是，该错误表明您的变量名称和类型之间有一些额外的字符。也就是BOOKISBNƒƒƒƒƒƒƒƒBOOKTI，所有f字符来自哪里？可能是这些是错误处理程序转换为可打印字符的不可打印字符。如果您将以下内容复制并粘贴到变量声明上并再次尝试，该怎么办？

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