I don't think MySql supports the row_number function. The only results I can see on Google are describing how to emulate it with a variable - for example, http://blog.sqlauthority.com/2014/03/08/mysql-generating-row-number-for-each-row-using-variable/[^]

EDIT: Whoops, just noticed digimanus' updated answer.

Only in MSSQL:

SQL

SELECT *
FROM (
		SELECT row_number() over (partition by Column1 order by Column2 desc) VersionRank, * 
		FROM Table1
 ) T
 WHERE T.VersionRank = 1

for MySQL read this[^]
