# SQUIRREL
SQL Query Util-Izing Rust's Reliable and Efficient Logic

![Demo showing data insertation into SQUIRREL](https://github.com/nickorlow/squirrel/blob/main/.meta/images/demo_data_insert.png?raw=true)

## About
This is a SQL database written in Rust. It will be based off of (and hopefully be made wire-compatible with) PostgreSQL's syntax.

## Feature roadmap

[X] CREATE TABLE with varchar & integer datatypes

[X] INSERT INTO (non-batched)

[X] SELECT * query 

[x] SELECT (filtered columns) query 

[x] DELETE command

[x] WHERE clause for SELECT and DELETE

[x] Create squirrel-core library for shared code between client & server

[x] Update parser to use common logic to identify ValueExpressions (i.e function calls, column references, and variables) 

[ ] Move parsing to client

[ ] Create better logging

[ ] Unify parser and datatype logic

[ ] Improve organization on command execution logic

[ ] UPDATE command

[ ] Prune deleted records from disk

[ ] Primary Keys via B+ Tree

[ ] Foreign Keys

[ ] Some form of JOINs

[ ] Support [Postgres' messaging system](https://www.postgresql.org/docs/current/protocol-flow.html#id-1.10.6.7.3) (wire compatability)
 
... other stuff is TBD
