如何更新账单编号栏？ 或在 sql 服务器的列中按顺序排列

Question

I work on a code, I wish to make this type of code like I delete one and more bill on SQL server database then after I arrange or update my bill number column value, for example:- bill number is (1,2,3,4,5) then I delete my same bill record or row (1,3,5) so how can I update or arrange sequence wise bill number like this (1,2,3,).

Answer 1

It's almost impossible to know what you are asking

but you can order the SQL set with ORDER BY ( https://docs.microsoft.com/en-us/sql/t-sql/queries/select-order-by-clause-transact-sql?view=sql-server-ver15 )

or if you need a sequential integer I would propose you add something to your query like this

SELECT *,
       ROW_NUMBER() OVER(ORDER BY bill_no) AS rowNumber
FROM YourTable

that should gie you a sequential integer for each row in your set.
