hi , every body

i want watch on identity column, i meant to say that if any column delete from table which has identity column, when new column add check identity column that any number is missing if then insert that missing number if not then continue with next number.

E.g 1,2,3,4

Now i delete 2 no column , When new column add it will be 2, if no column delete then next will be 5

Thanks
