Just updated the post with a much faster solution. There are many more solutions over at http://ask.sqlservercentral.com/questions/4241/whats-the-best-way-to-solve-the-fizzbuzz-question/.

Hi, how about the following for a fully set based solution…

create table #temp
(number int )
go

insert into #temp(number)
select top 100 row_number() OVER (ORDER BY [object_id]) from sys.columns;

select
number
, case
when number % 3 = 0 AND number % 5 = 0 then ‘fizzbuzz’
when number % 3 = 0 then ‘fizz’
when number % 5 = 0 then ‘buzz’
else ” end as test
from #temp;

drop table #temp;

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

[...] Solving FizzBuzz with Set-Based T-SQL – I talked about using the FizzBuzz problem to filter out DBA job candidates and a couple of answers popped up on blogs.

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.
