hai babitha,
I know this is pretty long time after u have posted ur problem.
What did u mean that u deleted the database- did u drop it or just removed the datafiles.
Any way i have not gone thru such a situation, but i simulated one similar situation.
I created a new database called test.I had an online backup.After that
i copied all the log files and droped the database.
Now using the online backup i created a database and copied back the log files and then rollforwarded till the end of logs.
the database is same as the previous
one.

Try this if u hav the logs.
