In the typical select statement of SELECT FIELDVAR FROM TABLE, how do I pass a variable for FIELDVAR?
In otherwords, if FIELDVAR=FIELD88, I want the resulting statement to be exectuded as "SELECT FIELD88 FROM TABLE"
I will likely kick myself when I get the answer....

to do something like that, you'll need to use dynamic SQL:

declare @fieldname nvarchar(200)
declare @sql nvarchar(1000)

set @fieldname = 'field88'
set @sql = 'select ' + @fieldname + ' from tablename'

execute sp_executesql @sql
