Hi Aanchal,
If an SQL error occurs now, you cannot see it in your code. You should do something with the exception you catch, e.g. printing it: sqlex.printStackTrace(), so that you can see if something goes wrong.
For your number, you should move the cursor in the resultset to the first row - either by: calling first( ) or next ( ), then you can retrieve your booknumber.
