Hello everyone, today I am going to discuss the Row number 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.
So, We can use Row_Number() with order by clause, without order by we can not use the Row_Nuber function.
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.
