sqla-raw 0.0.3

A tiny library for submitting raw SQL via SQLAlchemy

sqla-raw

I've copy-pasted this enough times that it seemed worth packaging. Really not much more than a single method (raw.db.result) to submit SQL to a database using a SQLAlchemy engine connection, and get results as a list of dictionaries, with each dict keyed by result set column names.

Installation

pipenv install sqla-raw[pg]

Usage

Configure your database connection string by setting $DATABASE_URL in your environment.

>>> from raw import db
>>> x = db.result('select version()');
>>> x
[{'version': 'PostgreSQL 10.10 on x86_64-apple-darwin14.5.0, compiled by Apple LLVM version 7.0.0 (clang-700.1.76), 64-bit'}]

Because it's SQLAlchemy, you can use named parameters in your SQL string with colon-prepended :key format, and assign values in kwargs.

Also, by setting optional parameter jinja=True, you can use Jinja2 templating syntax to interpolate the query, if desired. (It uses a SandboxedEnvironment, but avoid this option with untrusted inputs, for obvious reasons.)
