I would prefer CTE for deleting duplicate rows from sql server table

Strongly recommend following this article : https://medium.com/@CodAffection/how-to-delete-duplicate-rows-in-sql-server-3791ba275645

by keeping original

WITH CTE AS
(
SELECT *,ROW_NUMBER() OVER (PARTITION BY col1,col2,col3 ORDER BY col1,col2,col3) AS RN
FROM MyTable
)
 
DELETE FROM CTE WHERE RN<>1

without keeping original

WITH CTE AS
(SELECT *,R=RANK() OVER (ORDER BY col1,col2,col3)
FROM MyTable)
 
DELETE CTE
WHERE R IN (SELECT R FROM CTE GROUP BY R HAVING COUNT(*)>1)
