sqlite-utils VS PostgreSQL

So, his code might not be a good place to find best patterns (for ex, I don't think they are fully typed), but his repos are very pragmatic, and his development process is super insightful (well documented PRs for personal repos!). Best part, he blogs about every non-trivial update, so you get all the context!

Sounds like your problem is with SQLAlchemy, not with SQLite.

My https://sqlite-utils.datasette.io library might be a better fit for you. It's a much thinner abstraction than SQLAlchemy.

There are a few things you can do here.

SQLite is great at JSON - so I often dump JSON structures in a TEXT column and query them using https://www.sqlite.org/json1.html

I also have plugins for running jq() functions directly in SQL queries - https://datasette.io/plugins/datasette-jq and https://github.com/simonw/sqlite-utils-jq

I've been trying to drive the cost of turning semi-structured data into structured SQL queries down as much as possible with https://sqlite-utils.datasette.io - see this tutorial for more: https://datasette.io/tutorials/clean-data

This is also an area that I'm starting to explore with LLMs. I love the idea that you could take a bunch of messy data, tell Datasette Cloud "I want this imported into a table with this schema"... and it does that.

I have a prototype of this working now, I hope to turn it into an open source plugin (and Datasette Cloud feature) pretty soon. It's using this trick: https://til.simonwillison.net/gpt3/openai-python-functions-d...

I've baked a ton of different SQLite tricks - including things like full-text indexing support and advanced alter table methods - into my sqlite-utils CLI tool and Python library: https://sqlite-utils.datasette.io

My Datasette project provides tools for exploring, analyzing and publishing SQLite databases, plus ways to expose them via a JSON API: https://datasette.io

I've also written a ton of stuff about SQLite on my two blogs:

- https://simonwillison.net/tags/sqlite/

- https://til.simonwillison.net/sqlite

This is really fun. I have an experimental branch of my sqlite-utils CLI tool (which has dozens of sub-commands) running with this now and it really did only take 4 lines of code - I'm treating Trogon as an optional dependency because people using my package as a Python library rather than a CLI tool may not want the extra installed components:

There's an animated GIF demo of the result here: https://github.com/simonw/sqlite-utils/issues/545#issuecomme...

My project https://datasette.io/ is ideal for this kind of thing. You can use https://sqlite-utils.datasette.io/ to load JSON data into a SQLite database, then publish it with Datasette.

I've been using this for about six months now and I absolutely love it.

Make never stuck for me - I couldn't quite get it to fit inside my head.

Just has the exact set of features I want.

Here's one example of one of my Justfiles: https://github.com/simonw/sqlite-utils/blob/fc221f9b62ed8624... - documented here: https://sqlite-utils.datasette.io/en/stable/contributing.htm...

I also wrote about using Just with Django in this TIL: https://til.simonwillison.net/django/just-with-django

SQLite with the open source toolchain I've been building over the past five years:

https://datasette.io as the interface for running queries against (and visualizing) my data.

https://sqlite-utils.datasette.io/ as a set of tools for creating and modifying my databases (inserting JSON or CSV data, enabling full text search text)

https://dogsheep.github.io as a suite of tools for importing my personal data - see also this talk I gave about that project: https://simonwillison.net/2020/Nov/14/personal-data-warehous...

Here's an example: https://github.com/simonw/sqlite-utils/pull/468

> After identifying about 7 commits (with pretty basic/useless messages, and no PR link!), I then had to find the corresponding PRs based on timestamps, and search the PR history for PRs merged around those timestamps.

Not sure if this would save any time, but it is possible to search PRs by commit. For example, say git blame led me to this commit: https://github.com/simonw/sqlite-utils/commit/129141572f249e...

I could have found PR #373 via this search: https://github.com/simonw/sqlite-utils/pulls?q=bb16f52681b6d...

> I thus treat PRs as ephemeral

I think I see what you're saying but as others have pointed out, sometimes you want to add screenshots etc to the context, and you can't capture this kind of info in commit messages. So then you have two choices: issues or PRs.

> Then any review comments are preferably not addressed directly in the PR

I would think that sometimes you really do want to have a back and forth conversation in the PR, rather than just a "make this change" -> "ok done" type of feedback loop.

I view the PR as an decent place for all of this because it's basically a commit of commits, capturing the related changes/conversation/context all in a single place at the point of merge.

Another key feature of txtai is being able to quickly move from prototyping to production. This article will demonstrate how txtai can integrate with Postgres, a powerful, production-ready and open source object-relational database system. After txtai persists content to Postgres, we'll show it can be directly queried with SQL from any Postgres client

SQL (Structured Query Language) databases are relational databases. They organize data into tables with rows and columns, and they use SQL for querying and managing data. Examples include MySQL, PostgreSQL, and SQLite.

Node.js, MySQL and PostgreSQL servers installed on your machine

Each app’s front end is built with Qwik and uses Tailwind for styling. The server-side is powered by Qwik City (Qwik’s official meta-framework) and runs on Node.js hosted on a shared Linode VPS. The apps also use PM2 for process management and Caddy as a reverse proxy and SSL provisioner. The data is stored in a PostgreSQL database that also runs on a shared Linode VPS. The apps interact with the database using Drizzle, an Object-Relational Mapper (ORM) for JavaScript. The entire infrastructure for both apps is managed with Terraform using the Terraform Linode provider, which was new to me, but made provisioning and destroying infrastructure really fast and easy (once I learned how it all worked).

I've used MySQL for years. But recently, I found myself working PostgreSQL and simple things like dumping and restoring a database are different enough that I decided to document the process. It's straightforward enough once I knew how.

A running Rails application needs a database to connect to. You may already have your database of choice installed, but if not, I recommend PostgreSQL, or Postgres for short. On a Mac, probably the easiest way to install it is with Posrgres.app. Another option, the one I prefer, is to use Homebrew. With Homebrew installed, this command will install PostgreSQL version 16 along with libpq:

PostgreSQL

PostgreSQL: Offers a robust feature set and strong compliance with SQL standards, making it suitable for a wide range of applications, from simple to complex, particularly where data integrity and extensibility are key.

FerretDB is an open source document database that adds MongoDB compatibility to other database backends, such as Postgres and SQLite. By using FerretDB, developers can access familiar MongoDB features and tools using the same syntax and commands for many of their use cases.

To better understand how SQL injection works, let's quickly create a vulnerable app using Node.js, Express, and a PostgreSQL database. The application takes user input from a form, constructs a SQL query, and executes it against the database to fetch some data.
