How to Use Multiple Columns in Partition By And Ensure No Duplicate Row is Returned

Try this,
It worked for me

SELECT * FROM (
            SELECT
                [Code],
                [Name],
                [CategoryCode],
                [CreatedDate],
                [ModifiedDate],
                [CreatedBy],
                [ModifiedBy],
                [IsActive],
                ROW_NUMBER() OVER(PARTITION BY [Code],[Name],[CategoryCode] ORDER BY ID DESC) rownumber
            FROM MasterTable
          ) a
        WHERE rownumber = 1
