How to Add Ranking Positions of Rows with RANK in SQL

Do you need to rank the rows of a table in SQL? Ranking rows with the RANK() function is a great way to do this. This function assigns a rank to each row in the result set, based on the values of the columns you specify.

The RANK() function takes two arguments: the column or expression to rank by, and an optional PARTITION BY clause. The PARTITION BY clause allows you to rank the rows within a subset of the result set. For example, if you wanted to rank the rows of a table by the score column, you could use the following query:

SELECT RANK() OVER (ORDER BY score) AS rank, name, score FROM table_name;

This query would return the following result set:
