I guess it would have to be changed because if there is some other column that gets added to the table, then we would have to update the query and select the newly added column as well.

If we use select ALL(select * ) we won't have to edit the query, as it selects all the columns there are to select.

samee😥

search for ternary_operators, lambda and keep in mind you can have function arguments that are "optional"

How do I return a new column without creating one?

you are not supposed to use the create table clause. for sql katas in codewars, you usually need to use select, unless the description specifies otherwise

not a kata issue

I used CREATE TABLE with IF NOT EXISTS clause and I am getting following error in the log :

An error occurred while loading ./spec/query_spec.rb.
