我创建了Oracle Form，其中用户从目标“目标”链接“浏览”“CSV”文件，我们将在文本字段项中显示。 用户按下保存按钮后，列值将从“CSV”文件和显示列值读入数据块。 为此，我使用了Client_OLE2.create_obj('EXCEL.Application')过程。
在“CSV”文件中有些列像这样在调整宽度之前：
第四栏“6E + 09”
调整宽度之后像这样：
现在第4列值“6000000116”
调整列宽后，调整宽度后没有保存文件。
我的代码：

现在，当我按下保存按钮时，我收到以下错误：
FRM-50016法律字符为0-9 - + E.
如何解决这个问题呢？ Oracle Forms 11gR2
