Which Transact-SQL query should you use?

You administer a Microsoft SQL Server 2012 database that includes a table named
Products. The Products table has columns named Productld, ProductName, and
CreatedDateTime.
The table contains a unique constraint on the combination of ProductName and
CreatedDateTime.
You need to modify the Products table to meet the following requirements:
• Remove all duplicates of the Products table based on the ProductName column.
• Retain only the newest Products row.
