Following is quite common Interview Question asked in many interview questions. FizzBuzz is popular but very simple puzzle and have been very popular to solve. FizzBuzz problem can be attempted in any programming language. Let us attempt it in T-SQL.

**Definition of FizzBuzz Puzzle** : Write a program that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”.

`DECLARE @counter INT`

DECLARE @output VARCHAR(8)

SET @counter = 1

WHILE @counter < 101

BEGIN

SET @output = ''

IF @counter % 3 = 0

SET @output = 'Fizz'

IF @counter % 5 = 0

SET @output = @output + 'Buzz'

IF @output = ''

SET @output = @counter

PRINT @output

SET @counter = @counter + 1

END

I would take a set-based approach:

CREATE TABLE ##nums

(

number int IDENTITY(1,1),

nothing int null

)

INSERT ##nums (nothing)

SELECT TOP(100) OBJECT_ID FROM sys.all_columns

SELECT ‘FizzBuzz’ =

CASE

WHEN ((number % 3 = 0) AND (number % 5 = 0)) THEN ‘FizzBuzz’

WHEN (number % 5 = 0) THEN ‘Buzz’

WHEN (number % 3 = 0) THEN ‘Fizz’

ELSE CAST(number AS CHAR(3))

END

FROM ##nums

Zod,

Good Script. Let us see what else we get from other exports.

Following code maybe a little bit dummy but seems more readable?

DECLARE @counter varchar(5)

SET @counter = 1

WHILE @counter < 101

BEGIN

print case

when @counter%3=0 and @counter %5 !=0 then ‘Fizz’

when @counter %3 !=0 and @counter%5=0 then ‘Buzz’

when @counter%3=0 and @counter%5=0 then ‘FizzBuzz’

else @counter end

SET @counter = @counter + 1

END

since we gonna do it in sql server, i suppose the result would be better to display in table:

WITH CTE (Col1)

AS

(

SELECT 1 AS Col1

UNION ALL

SELECT Col1 + 1 FROM CTE

WHERE Col1 < 100

)

SELECT

CASE

WHEN Col1%3 = 0 AND Col1%5 = 0 THEN ‘FizzBuzz’

WHEN Col1%3 = 0 THEN ‘Fizz’

WHEN COl1%5 = 0 THEN ‘Buzz’

ELSE CONVERT(VARCHAR(3), Col1)

END

FROM CTE

Here’s another qay, very similar to howyue:

WITH

Number

AS

(

SELECT 1 A UNION ALL

SELECT A + 1 FROM Number WHERE A 0 AND A%5 > 0 THEN CAST(A AS VARCHAR) ELSE ” END

FROM

Number;

Little complicated but again thats also a way

This was my solution. Surprised I’ve never heard of this until today.

DECLARE @Counter INT

SET @Counter = 1

WHILE @Counter <= 100

BEGIN

SELECT

@Counter,

CASE

WHEN @Counter % 3 = 0 AND @Counter % 5 = 0 THEN 'FizzBuzz'

WHEN @Counter % 3 = 0 THEN 'Fizz'

WHEN @Counter % 5 = 0 THEN 'Buzz'

ELSE CAST(@Counter AS CHAR(3)) END AS 'Out'
