Circle CI

This repository holds a pure Go SQL parser based on the SQLite SQL definition. It implements nearly all features of the language except ATTACH, DETACH, and some other minor features.

Credits

This parser was originally created by Ben Johnson. Many thanks to him for making it available for use by rqlite.
