CREATE TABLE MyTable (
MyID INT,
CreateDate DATETIME
)

What's the simplest DELETE of all rows saving only the most current CreateDate for each value if MyID?

DELETE FROM MyTable
FROM
MyTable
INNER JOIN MyTable M2 ON M2.MyID = MyTable.MyID and M2.CreateDate > MyTable.CreateDate

I kind'a like this syntax:


DELETE	A
	FROM	dbo.Feedback2 A
	INNER JOIN dbo.Feedback2 B ON A.CourseID=B.CourseID AND A.UserID=B.UserID AND A.FormID=B.FormID AND A.CreateDate < B.CreateDate

Didn't know an alias would work on a delete till now.
