prql-python

prql-python offers rust bindings to the prql-compiler rust library. It exposes a python method to_sql(query: str) -> str.

This is consumed by PyPrql & dbt-prql.

The crate is not published to crates.io; only to PyPI.

Installation

pip install prql-python

Usage

import prql_python as prql

prql_query = """
    from employees
    join salaries [emp_id]
    group [dept_id, gender] (
      aggregate [
        avg_salary = average salary
      ]
    )
"""

sql = prql.to_sql(prql_query)

Relies on pyo3 for all the magic.

#[pyfunction]
pub fn to_sql(query: &str) -> PyResult<String> {}
fn prql_python(_py: Python, m: &PyModule) -> PyResult<()> {}
