sql loop help


I have a variable that has an address. State and zip have been pulled out and the state is stored in a variable called @state
 
@address   may have this in it  5220 Main St Winston Salem..

I have a function that gets the word in a string.. Its called udf.getword and it just needs @address and a number that tells me what word you want to pull out from the left.. so

select udf.getword (@address,1) gives me Salem.. and (@address,2) gives me Winston..etc..


How do get below using my udf?
I want to loop 4 times to get the below results populated in a variable called @lastSearchValue.

First loop gives me Main St Winston Salem
Second loop gives me St Winston Salem
Third loop gives me Winston Salem
Fourth loop gives me Salem

When you loop four times, you get four different results. Do you want all those results in one variable? Do you always want to loop it four times or its just an example?

try
declare @I integer
declare @temp varchar(max), @var1 varchar(max), @var2 varchar(max), @var3 varchar(max), @var4 varchar(max)
declare @address varchar(max)

set @I = 1

while @I < 5 
begin
  select @temp = udf.getword(@address, @I)
  if @I = 1 
      set @var1 = @temp
  else if @I = 2 
      set @var2 = @temp
  else if @I = 3 
      set @var3 = @temp
  else if @I = 4 
      set @var4 = @temp       
  
  set @I = @I + 1 
end
