Copy paste in the application(from file to database)

Question

Hi!
Is it possible to provide a 'copy-paste' functionality in end-user app? I know there is such feature in SQL Workshop but I would like to prepare an application which enables users to copy data from fxls/csv file and the paste it into the application. The data should be saved then in the relevant table in database.
Regards,
Tom

Are you talking about importing data into an existing table where the column data type
needs to match the column data type in your table? Preferably a comma or semicolon
separated or tab delimited data.
If this is so, then there is a simple way to acomplish this using external tables as an
interface. There you need access to your underlying file system. You could do this in
the following way:
1. Create a text area and paste some data in it,
2. Copy that data into a BFILE on your file system,
3. Create an external table which will read the created file
4. Query your external table, validate the data and transfer it into your target table.
This is, of course a simple way - you know the structure of your data in advance.
You could also do it the way ApEx does it - providing an interface for more then one
case and letting user create their own tables, load from file, load from xml file, etc.
However, this would require much more time to make it working.
Unfortunatelly, there is no access to file system on htmldb.oracle.com for me to
show you how this could be done. I have a description on how to handle this problem

This may help you to start with.
