Just to be different. I’ve already got a tally table of sequential ints set up. So…

CREATE FUNCTION [dbo].[ufnGetFizzBuzz]
(
@Number int
)
returns nvarchar(50) as
begin
declare @retStr varchar(50) = NULL

if @Number % 3 = 0
set @retStr = N’Fizz’

if @Number % 5 = 0
set @retStr = N’Buzz’

if @Number % 3 = 0 and @Number % 5 = 0
set @retStr = N’FizzBuzz’

if @retStr = null
set @retStr = cast(@Number as nvarchar(50))

return @retStr
END
GO

select dbo.ufnGetFizzBuzz(number)
from WorkDB..TallyTable
where number <= 100

Great intuitive information. Keep them coming Brent. I’m a person that is getting my feet wet on SQL Server and looking to get certified and then move up to Oracle. I think this site will definitely help me. Thanks again

declare i,a,b,y as integer
set i=1

while i <= 100

begin
if(i%3)=0 then a =1
else a=0
end if
if(i%5)=0 then b =2
else b=0
end
y=a+b
case y
y=0 print (i)
y=1 print ("Fizz")
y=2 print ("Buzz")
y=3 print ("FizzBuzz")
end case
end
i=i+1
loop
end

If you want to get a feel for his or her’s query optimization skills I’ve found asking what a bookmark lookup seems to be a good one that trips a lot of people up.
