SQL & PL/SQL

Hi all..

Please help me.

For example :

i have table A.

in this table i have one record with serial from number 1 until 10.

And then, in table B, i put number between 1 and 10.

and i use number 1, 2, 3, 6, 8, 10.

I want to find missing values between 1 and 10. So, can i select using query for this case ?

This is the output value in query :

4, 5, 7, 9

Sorry for bad language.

Thanks all.
