declare @n as int,@b as int,@s as int,@g as int
set @n=100
while @n<1000
begin
set @b=cast(substring(cast(@n as varchar(3)),1,1) as int)
set @s=cast(substring(cast(@n as varchar(3)),2,1) as int)
set @g=cast(substring(cast(@n as varchar(3)),3,1) as int)
if power(@b,3)+power(@s,3)+power(@g,3)=@n
begin
print @n
end
set @n=@n+1
end
