Row number SQL
Row number function in SQL server
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.
