# SQL Parser # SQL Parser
The goal of this project is to build a SQL lexer and parser capable of parsing ANSI SQL:2011 (or 2016 if I can get access to the specification for free). The main goal of this project is to build a SQL lexer and parser capable of parsing ANSI SQL:2011 (or 2016 if I can get access to the specification for free).
The current code is capable of parsing some simple SELECT and CREATE TABLE statements. A secondary goal is to make it easy for others to use this library as a foundation for building custom SQL parsers for vendor-specific dialects.
## Example
The current code is capable of parsing some trivial SELECT and CREATE TABLE statements.
## Example
```rust ```rust
let sql = "SELECT a, b, 123, myfunc(b) \ let sql = "SELECT a, b, 123, myfunc(b) \

I am a fan of this design pattern over parser generators for the following reasons: I am a fan of this design pattern over parser generators for the following reasons:
- Parsing code is simple to write and can be concise and elegant (this is far from true for this current implementation unfortunately, but I hope to fix that using some macros) - Code is simple to write and can be concise and elegant (this is far from true for this current implementation unfortunately, but I hope to fix that using some macros)
