多个PLS-00103:遇到符号"IN“

Question

我遇到了多个编译错误，无法修复，尽管之前的线程上有一些基于Stack Overflow建议的更改。对不起，我不熟悉PL/SQL，所以我需要帮助。

我的初始代码：

create or replace procedure exp_proc (
    v_job_name   in varchar2,
    v_dump_file  in varchar2,
    v_operation  in varchar2 default 'export',
    v_job_mode   in varchar2 default 'full',
    v_table      in varchar2(50) default NULL,
    v_parallel   in number default 1,
    v_directory  in varchar2 default 'datapump_dir',
    v_logfile    in varchar2 default 'logfile%u.log')

错误是：

LINE/COL ERROR
-------- -----------------------------------------------------------------
6/27     PLS-00103: Encountered the symbol "IN" when expecting one of the following:
         := . ) , @ % default character

6/43     PLS-00103: Encountered the symbol "DEFAULT" when expecting one of the following:
         . ( * % & - + / at loop mod remainder rem ..
         <an exponent (**)> || multiset
         The symbol "(" was inserted before "DEFAULT" to continue.

7/33     PLS-00103: Encountered the symbol "NUMBER" when expecting one of

有没有人能帮我检查一下代码，帮我修复一下

提前感谢
