Sql-server – Good way to use table alias in Update statement

sql-server

Using SqlServer, and trying to update rows from within the same table. I want to use a table alias for readability.
This is the way I am doing it at the moment:

UPDATE ra 
SET ra.ItemValue = rb.ItemValue
FROM dbo.Rates ra, dbo.Rates rb
WHERE ra.ResourceID = rb.ResourceID
AND ra.PriceSched = 't8'
AND rb.PriceSched = 't9'

Are there easier / better ways?

Best Solution

UPDATE ra 
   SET ra.ItemValue = rb.ItemValue
  FROM dbo.Rates ra
 INNER JOIN dbo.Rates rb
         ON ra.ResourceID = rb.ResourceID
WHERE ra.PriceSched = 't8'
  AND rb.PriceSched = 't9';

This might help in improving performance.
