I would use a trigger for that. I have barely touched basic craft as I know the rates are pitiful so it isn't really worth doing, most of the time you are crafting at a loss and I complained about this in official a lot. At some point I want to redo all of the rates to make it worthwhile doing again.
Code:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TRIGGER dbo.craft_fix
ON dbo.cabal_craft_table
AFTER UPDATE
AS
BEGIN
UPDATE dbo.cabal_craft_table
SET Level0='9',Exp0='36000'
WHERE Level0='9' and Exp0='45000';
END
GO
