How to find Rank of row in MySQL I am new to MySQL. I know that ROW_NUMBER() OVER (PARTITION) will not work in MySQL. I want to convert the code from SQL Server to MySQL:

SELECT  *, 
    ROW_NUMBER() OVER (
        Partition By X.TPID,originTLA, destinationTLA  
        ORDER BY packageStartDate,totalPackageSavingsPct desc
    ) AS ttl_perct_rnk 
FROM TABLE


I want to convert this code to MySQL.

In Most of the cases the requirement to find rank is based on a single column. But here we have to find rank based on three columns. It is easy to find rank based on single column. But I am not sure how can we implement the rank based on three column or multiple columns.
This what you are looking for?:

SELECT  @rank := @rank + 1 AS 'Rank', province, city, population
    FROM  canada
    JOIN  ( SELECT  @rank := 0 ) AS init
    WHERE  population &gt; 0
    ORDER BY  province, city, population DESC;

Or you can upgrade to MySQL 8.0 or MariaDB 10.2 to get CTEs and Windowing functions.
