4. Now you explicitly enter a value for Identity column
5. Using Identity during data insert
6. Using IDENTITY value
7. Get current IDENTITY value
8. Seed value was negative and the increment was positive
9. Created with an IDENTITY property that is set to start at 1,000,000 and decrement by 100 for every row added
10. IDENTITY [ (seed , increment ) ]
11. IDENTITY as PRIMARY KEY
