“必须声明 Client_Text_IO.File_Type”在 PL/SQL Oracle 表单中出现此错误

Question

我的代码行是：

PROCEDURE LOAD_DATA IS

FILE_LOG    Client_Text_IO.File_Type;
LINE_LOG    VARCHAR(32767);
v_txt       varchar(32767);
v_counter number(12) := 0;

BEGIN

file_log :=  Client_Text_IO.fopen(file_upload.origin, 'r');

END;

我是第一次使用 Oracle 表单。我对此一无所知。我几乎完成了我的工作，但在编译时出现错误。完整的错误描述，

您需要将 webutil.pll 库附加到表单。
