See if I have a database like this

Table Headers    Category  City  Serial_no

Table Content    Dealer    Agra     1
                 Dealer    Agra     2
                 Dealer    Chennai  3

Now when I add another record Dealer Agra 3, then the table content should change to

Dealer    Agra     1
Dealer    Agra     2
Dealer    Agra     3
Dealer    Chennai  3

This should be achieved without using auto id

Please help me.

In my opinion this is not a good idea.

Ordering should take place when you fetch the data from the database not when you insert data in it. When inserting you just make sure that you insert all relevant data for different kinds of ordering needs.

If you put the ordering into the table, it's just one variation. What happens if another kind of ordering is needed.

To fetch the desired results you should order the results in the select, something like:

SQL

SELECT Category, City, ROW_NUMBER() OVER(ORDER BY City)
FROM YourTable
ORDER BY City
