|Python| |ruff-linter| |pyright-checker| |license| |sphinx|

A library to help build SQL-like functionality without the overhead of a database.

See https://slott56.github.io/functional-SQL/_build/html/index.html for the documentation.

Some SQL

..  code-block:: SQL

    SELECT n.name, v.c2

    FROM names_table n, values_table v

    WHERE n.code = v.c1

Some Python that does the same thing.

..  code-block:: python

    Select(name=lambda cr: cr.n.name, value=lambda cr: cr.v.c2)

    .from_(n=names_table, v=values_table)

    .where(lambda cr: cr.n.code == cr.v.c1)

Yes. The Python is longer. Yes it has ``lambda cr: cr.`` scattered around. The Python produces the same results as the SQL query, using essentially the same algorithm.

You can write Python using the SQL algorithm design pattern.

And without using a database.
