MySQL ROW_NUMBER() Function Explained

The ROW_NUMBER() function in MySQL is used to assign a unique consecutive number to each row in the result set. It is typically used in conjunction with the ORDER BY clause to specify the order of rows in the result set.

Here is an example of the ROW_NUMBER() function:

SELECT ROW_NUMBER() OVER() AS row_num, column1, column2
FROM table_name
ORDER BY column1;

In the given example, the ROW_NUMBER() function assigns a unique row number to each row in the result set and sorts the results based on the values in column1. The row_num column will display the row number for each row.
