  Is it possible to replace a Date Value if null with another date in a table?

  Example :

  DATEPART(mm, (ISNULL((DATEADD(mm,1,s.Date)),s.Date)))

  same table? sure:

  UPDATE Customer

  SET UpdatedDate = CreatedDate

  WHERE UpdatedDate IS NULL

  AND CreatedDate IS NOT NULL

  different table ? if you can join the tables together, then yes.

  UPDATE Customer

  SET VerifiedDate = Verfications.VerifiedDate

  FROM Customer

  INNER JOIN Verfications ON Customer.CustomerId = Verfications.CustomerId

  WHERE Customer.VerifiedDate IS NULL

  AND Verfications.VerifiedDate IS NOT NULL
