the name of the producer column should be "producer" instead of "producent"

Nice little Kata to go back to basics. It may help to explain that LEN can't be used, or possibly an 8kyu.

idk why but i enjoy solving easy problems

"producent" should probably be spelled "producer"

Terrible kata.
The name of the table is the same as the name of the result field.
The order of the fields in the table is not intuitive.
The formulation of the problem also leaves much to be desired.

bad kata, it asked us to use 'round' to solve the problem. but, the fuc'ed 'round' doesn't work properly.

I didn't understand the description. "You will need to create a SELECT statement in conjunction with LIKE.". LIKE what?

upd:
This means that the relevant string must be larger than 6 characters and the LENGHT function MUST NOT BE USED in the solution.
What was the problem with writing a clear description?

How is nobody else mentioning this problem? This just drove me crazy for 10 minutes

I think I have fixed Javascript and Ruby, added more random tests as well.

Precision has been fixed by someone already.

I have added negivative value to random tests.

what is the problem that you are reporting exactly ? is there something wrong with the kata ?

just keep in mind that producent coulmns can contain values like "CompanyA", "CompanyB" etc which u might want to use in your solution

I love these kind of Katas :)

Honestly a very stupid question. It's asking you to USE Like and Len in the instructions which makes no sense at all.
