【问题描述】：

我正在尝试在 Oracle 11g XE 中运行以下 PL/SQL 代码。据我所知，代码没有任何问题，但是，Oracle 给了我错误——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：

任何帮助将不胜感激。

谢谢！

不确定这是否有帮助。 ***.com/questions/3382833/…

@Ben 当然除了表架构和数据

srikanthradix 不是真的，如果我没看错，我必须使用单引号，我已经这样做了

【参考方案1】：

您提供的代码在我运行时非常适合我。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。即BOOKISBNƒƒƒƒƒƒƒƒBOOKTI，所有f 字符从何而来？可能这些是错误处理程序正在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您的变量声明中并再次尝试，会怎样？

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