Update

IF [Custom2] = ''
    Update [tblObject]
    Set [Modified] = GetDate()
    Where [Level] = 0
ELSE
    Update [tblObject]
    Set [Modified] = GetDate(),
          [Name] = [Custom2]
    Where [Level] = 0

Jag sökte runt lite och hittade något sånt här:

UPDATE tblObject
SET 	[Modified] = Getdate(),
	[Name] = 
    		( CASE
         		WHEN [Custom2] = '' OR [Custom2] IS NULL THEN
				[Name] = [Name]
         		ELSE 
				[Name] = [Custom2]
       			END
    		)
WHERE [Level] = 0

Skulle det fungera?

Eller kanske bara:

UPDATE tblObject SET Modified = GetDate(), Name = Custom2 WHERE Level = 0 And (Custom2 <> '' Or Custom2 Is NOT Null)

Typ?

Eller

UPDATE tblObject SET Modified = GetDate(), Name = Custom2 WHERE Level = 0 And Custom2 <> '' And Custom2 Is NOT Null

Så får det bli....
