Right, this is entirely possible in Elixir. Build a datastructure in Yecc that represents the input. Build a recursive function that builds an ecto query by walking the datastructure yecc returns. If this seems like something you aren’t sure how to do, break the problem down. Play around with the ecto functions so that you get familiar with how to use them. Play around with walking data structures with an accumulator so that you can do simple things like count how many parts to the input there are. Then combine.
We’re happy to help with these steps, but you need to break the problem down into pieces you can work on incrementally.
