Writing a Python SQL engine from scratch
> The main reason why I ended up building a SQL engine was...just for entertainment. It's been fun learning about all the things
I also wrote an SQL parser [1] for SQLite schema. This was mainly for fun, but also to support the specificities of SQLite schema. I was not happy with the result of other parsers (including sqlglot).

Open Source SQL Parsers
SQL is a mess. It is difficult to find a parser that fulfills your needs.
A month ago, I needed a parser to parse SQLite schemas. SQLite has some edge case and I needed a lossless parsing to detect these edge cases.
I finally wrote my own parser [1] to fullfill my needs and to have some fun. This is for a POC project.
