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 isDate(‘a’)
Print isDate(”)
17 characters
print str(”) will be shorter :)
Another Mysql solution, of 14 characters
Select sin(”)
select char(48)
select sin(pi())
–or
select @@error
SELECT $
select char(48)
select $
SELECT isdate(1)
print @@ERROR
select @@error
select log(1)
print log(1)
SELECT SIN($)
print $
other example
select $
other example
SELECT ISDATE($)
KR
print @@ERROR is 13 chars…
obviously this one is 1 char shorter: ;-)
SELECT ISDATE(”)
but these are even shorter (not sure if these count as arithmetic calculation…)
SELECT FLOOR(”)
SELECT ABS(”)
SELECT TAN(”)
SELECT SIN(”)
SELECT ABS($)
is even shorter
print @@ERROR
select sin(pi()) should theoretically work, but doesn’t!
select @@error is my best so far
Print abs(”)– 13 chars
select Str(”)
