ROW_NUMBER() in SQL Server: Advanced Techniques for Ranking #sqlserver #transactsql #coding
ROW_NUMBER() is a powerful window function in SQL that assigns a unique number to each row within a result set, based on the specified order. It is commonly used for tasks such as ranking, pagination, and identifying row positions within a partitioned dataset.
The basic syntax of the ROW_NUMBER() function is as follows:
ROW_NUMBER() OVER (ORDER BY order_expression [ASC|DESC])
ROW_NUMBER(): The window function that generates a unique number for each row.
ORDER BY: Specifies the column(s) by which the rows within each partition are ordered. The row numbering is determined by this order.
[ASC|DESC]: Optional. Specifies the sort order for the ORDER BY clause. ASC (ascending) is the default.
Example usage of the ROW_NUMBER() function:
Suppose we have a table named "Employees" with columns "EmployeeID," "FirstName," and "Salary." We want to rank employees based on their salaries:
