Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
You are correct.
I'm curious why I still get the error with a different function name, though. I'm assuming there's something about the way the solution runs that causes it.
Either way, thanks for the pointers.
Having difficulties with the SQL version of this kata.
I'm getting this message:
PG::DuplicateFunction: ERROR: function "is_even" already exists with same argument typesIs this an issue with the kata or have I done something wrong with my CREATE FUNCTION statement?
