# SQL SERVER – Puzzle – Write a Shortest Code to Produce Zero

Puzzle: Write a Shortest Code to Produce Zero.

It has been a long time since we have puzzle on this blog. So I have decided to post this puzzle. You have to write a shortest code which produces digit 0 (zero).

If you think this puzzle is easy, it is not true. I have two very simple but interesting condition for you.

Condition 1:  Do not use numbers and arithmetic calculation

Condition 2: Do not use 0 in the code

Condition 3: Do not use function len()

Well, that’s it. So if you were thinking to write code like SELECT 1-1 or PRINT 0 or SELECT LEN(”). You can’t do that. You are not allowed to use numbers, arithmetic calculation or the digit 0 in the code.

Let me show you one valid solution.

`SELECT ISDATE('a')`

Now, here is the challenge for you. The above code produces the result 0 (zero) and the length of the code is 18.

Here is the final condition for you,

Condition 4: Your Solution should have length lesser than 18 characters.

Now think of the interesting solution and post the result in the comment.

I will be happy to see what you can come up with. If you are also subscribed to my newsletter at https://blog.sqlauthority.com/contact-me/sign-up/ please expect a surprise gift for you if you get the correct answer.
