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?
