How to dynamic specify the colums in Full-Text Search?

My problem is simple: i want to dynamic specified the columns in the ContainsTable, this is possible? Please see the example.

Declare @.Test1 int
Declare @.Test2 int
Declare @.Query varchar(50)
Declare @.Temp varcahr(50)
--Test
Set @.Test1=1
Set @.Test1=0
Set @.Query='something'
--Add the column to put in containstable
IF (@.Test1=1)
Begin
Set @.Temp='ID'
End
IF (@.Test2=1)
Begin
Set @.Temp= @.Temp + ',Name'
End
SELECT *
 FROM
 <table>
 INNER JOIN
 CONTAINSTABLE (<table>,@.Temp, @.Query) AS KEY_TBL
 ON <table>.ID = KEY_TBL.[KEY]

ThanksOnly in Sql Server 2005 (Yukon) that is possible... :/
