i am using oracle as database. i want to create table at run time that will remains in database to store info permanatly later..
plz.. anyone can tell me.. how to do this?

Use the same SQL statement used to create the table on the server and pass that through your code. When the application exits (whether purposefully or not) the table should be deleted.

I unfortunately, haven't done so in the past but after a quick search, I've found this post that should get you started in the right direction.
