# A Query Parser Exercise

The prompt for this exercise is in rust_code_challenge.pdf.

# Run and testing

* `cargo run` will run using the sql found in `queries.sql` and metadata from

`columns.csv`. This is configurable.

* `cargo test` will test against a couple of examples.

# Output

The spec for this exercise didn't really have a goal output. So, `cargo run`

prints the lineage and the opacity of that lineage for each sql statement in

`queries.sql`.

## Status

- [x] simple select with identifiers and simple functions (like `COUNT` ) only

- [x] column usage

- [x] unions

- [x] handling column aliases

- [ ] nested queries

- [ ] handling expressions with multiple source columns (like + or functions)
