Yeah..

I know that it's possible to use the wildcard, but for this esy Kata, I prefer to wrote the answer selecting the fields on purpose.

That's really an invalid point. And there are better points than this anyway, so resolving.

Okay, so, you know CW has an entry test for a reason, right? That's the low bound of which an 8kyu kata can be in difficulty, since otherwise you can't even register for the site in the first place.

And this kata is even simpler than the entry test, which means it's not really suitable as a kata.

You didn't put anything in for the sample tests so it's just using the default template, which does contain some tests but it's not correct for the kata.

Done, thanks...

The cross in the language selector in the kata editor.

I would like to know how can i delete it...

There's a broken JS version.

More info on this please...

There's even https://www.codewars.com/kata/sql-grasshopper-select-columns

https://www.codewars.com/kata/reviews/5d0007212ad465000116c2d2/groups/5d0013449bde3400019064eb passed the tests, so it's not different from the first kata now.

Fixed!

More info please...

Presence of extraneous columns in the result isn't checked.

According to the description country isn't in the table.
