Hi All,

I want to Upgrade my database for the Current Application. Whenever I want to reinstall the same application.First I have to erase it first and again i have to install it. But I want to rename the database of the application and i want to remove it, next time when i Upload my application into device again i will install the renamed database into my application.
In this way i want to do.But I am not finding the way to do this. Is there any other way to upgrade my application without erasing the database. I don't want to use DesktopManager. Why becoz my customers will download this application via OTA. In that way not possible to keep backup of my database and again restore it into the device.

Please can any one help in this issue. Urgent.


Thanks in advance
Venkat

If your "database" is "data stored in persistent storage" then it's easy: make sure all the data stored in PS is of a standard type (java.lang.String, java.lang.Integer, any of the classes in the RIM OS, etc.). The data will persist across application removal/re-installation. Data in Persistent Storage is removed when there is no class definition for the objects. If you "serialize" your data by turning it into a String, it will still be available when you remove the application that stored it.
