[mounarajan]

i have created the app by

require 'leveldb'
db = LevelDB::DB.new("test14.db")
db.put "one","hi welcome3"
puts db.get "one"

Now after closing this app how to open the database???

i tried

require 'leveldb'
db = LevelDB::DB.new("test14.db")
puts db.get "one"

But the above code throws error
