Question of the Week -25/12/2013- Question1

Suppose we have a table says tbl_students whose structure is given below:-

Create table tbl_students(Studentid int identity(1,1) , Studentname nvarchar(150))

Suppose it contains the following data:-

Studentid   Studentname 
1               Vivek Johari
2              Chandra Singh
4              Avinash Dubey
6              Akhil 
7              Sunny Rana
10            Saurabh

As one can see from the data that some rows are deleted from the table as some studentids are missing.

So write a query which gives the studentid which are deleted from this table.
