SQL Puzzle – FizzBuzz3d

I thought for the end of the month it would be fun to do another T-SQL Puzzle. In this case a slight upgrade of the FizzBuzz puzzle using T-SQL. So here are the rules:

Argh: I made a mistake in my rules so I’m correcting them. New text in italics, removed text struck out.

  • Create a table with the columns x, y and z, each representing a coordinate in a cube.
  • Each coordinate can have values 1-100 and there will be every possible combination of values. (1,1,1) to (100,100,100).
  • A fourth column will be created that contains the Fizz/Buzz/FizzBuzz. Name it FizzBuzz for convinence.
  • If any coordinate is evenly divisible by 3 then that the FizzBuzz cell contains “Fizz”.
  • If any coordinate is evenly divisible by 5 then that the FizzBuzz cell contains “Buzz”.
  • If any coordinate or combination of coordinates is evenly divisible by both 3 and 5 then the FizzBuzz cell contains “FizzBuzz”.

 

Optional rules to make it hard .. err .. more fun.

  • This must be done in a single query. No creating the table & populating it in multiple steps.
  • No using the modulo (%) operator.
  • It’s going to be a big table so let’s save some space. Use the smallint datatype for the coordinates and of course varchar(8) for the cells.
  • Expand to 1000 values per direction (but you had better have a lot of space).

 
My solution (which I’ll email if you ask me nicely) took ~45 min with all of the … extras. Now I have a moderately slow laptop ($350 when I bought it 4 years ago) with an HDD. I’m also kind of so-so when it comes to T-SQL so I wouldn’t be surprised if you did better than me. As a comparison, the same thing with just 100 values per direction took ~3 seconds.

I’ve been working with SQL Server for 12 years but have only really started “studying” the subject for the last 3. I don’t have any real "specialities" but I enjoy trouble shooting and teaching. Thus far I’ve earned by MCITP Database Administrator 2008, MCTS Database Administrator 2005, and MCTS Database Developer 2008. I’m currently studying for my MCITP Database Developer 2008 and should start in on the 2012 exams next year. My blog is at www.sqlstudies.com.
