What is Row_Number() in SQL ?

Hello everyone, today I am going to discuss the Row_number feature in SQL server.

what is Row_Number()?

Row_Number is used to generate the number of each row dynamically in a sequential order based on some column orders.

Row_Number() must be used with order by clause, without order by we can not use the Row_Nuber function.

Row_Number() over(order by EmpName) as RowNumber


Generate unique Id for each row dynamically: – In case if the table does not have a primary key or any unique identification number. you can use Row_Number to provide the unique ID for a table.

Row_Number() over(Order by EmailId) as Id,

Output from the above SQL Query
