How can I delete duplicate rows in a table

I need something to delete repeated rows from the database.

I found out how many rows are repeated in table using this query :

SELECT GoodCode FROM Good_

and here is distinct query SELECT Distinct GoodCode FROM Good_

The second one has lower records. Please guide me how I can delete repeated rows from the first one.

Simple method:

SELECT DISTINCT *
INTO   #TempGood
FROM   Good_

TRUNCATE TABLE Good_

INSERT Good_
SELECT *
FROM   #TempGood

DROP TABLE #TempGood
