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.

print @@error
select isdate(‘a’)
select = 6 char
isdate(‘a’) = 11 char
+1 space = 18 char
SELECT @@ERROR
select @@ERROR
PRINT PATINDEX(‘a’,”)
PRINT CHARINDEX (‘a’,”)
select cast( ” as bit)
SELECT CAST(” AS INT)
select @@error
select @@error
select isnumeric(‘a’)
Shortest code to produce zero :
select @@error
select isDate(”) . This code produces zero and it is less than 19 characters
SELECT @@ERROR
Select isdate(”)
SELECT FALSE
SELECT @@ROWCOUNT
will return 0 and satisfy the requirements.
