row_number and partition by in Mysql

Are row_number and partition by available in MySQL? Answer is NO.
Microsoft SQL Server support row_number and partition by to find one unique record from a set of duplicate records. We can also set the order by to get one unique record.

MySQL doesn’t provide this feature directly. We can achieve this by using an inline variable for SELECT statements.

In this post, I provide you full demonstration to perform this exercise.

I have also prepared script to insert sample duplicate records and create one stored procedure to find only unique record base on giving order by.

Below is a full demonstration:
