I could really use some help on this one. I am trying to select the Company column if it has a value or fname + lastname if it does not. Here is what I am thinking, I know this doesn't work.

SELECT [ID]
,[Title]
,[fname]
,[lastname]
,[Company]
,[Attention]
,if(Company != null or Company != '')
[Company] as displayName
else
fname + ' ' + lastname as displayName
FROM [Donors]



Any help, guidence or other constructive comments would be greatly appreciated.

You're on the right track, but what you need is "Case When Else". Look up Case in Books Online, it's got samples, syntax, etc.

Try this too.

SELECT [ID]
,[Title]
,[fname]
,[lastname]
,[Company]
,[Attention]
, IsNull( NullIf(Company, ''),fname+' '+ lastname) as displayname

FROM [Donors]
