if (@n1 != 0 and @n2 != 0) not required though

declare @num int,
@n1 int,
@n2 int
set @num = 1

while(@num < = 100)
begin

select @n1 = (@num%3)
select @n2 = (@num%5)

if (@n1 = 0)
if (@n1 = 0 and @n2 = 0)
Print 'FizzBuzz'
else
Print 'Fizz'
if (@n1 != 0 and @n2 = 0)
Print 'Buzz'
else
if (@n1 != 0 and @n2 != 0)
Print @num
set @num = @num + 1
end

That would be because the default MAXRECURSION is 100. If you want to go above that, add OPTION(MAXRECURSION 102) after the ORDER BY clause. You can use 0 for unlimited, but be careful.

Rob,

This also shows another thing. The CTE is recursive in nature. So what we really have here is an example of using recursion.

Rob,

This doesn't seem to scale well.

When I change the where clause to "WHERE Number < 102", I get:

"The statement terminated. The maximum recursion 100 has been exhausted before statement completion."

This reminds us how hard is is to keep your mind on SET BASED all the time.
