## SQL Types

WIP: SQL Types transpiles `CREATE TABLE` SQL code into type definitions in other languages such as TypeScript or Rust. 

## Syntax

Basic syntax rules:

```ebnf

 ::= 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9

 ::= a | b | c | d | e | f | g | h | i | j | k | l | m | n | o | p | q | r | s | t | u | v | w | x | y | z | A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z

 ::= !!any character.

 ::= $

 ::= "

 ::= _

 ::=  | 

 ::= { | } [{ |  |  |  | }...]

 ::= ...

// note: original definition is  instead of 

 ::= 

```

### Create Table Syntax

Currently Work in progress

## Usage

there is a little interactive shell to enter SQL and get parsed AST expressions back.

```sh

❯ cargo run

>>> x

Parsing error at line 1 column 1. No repair sequences found.

>>> CREATE TABLE abc(A INT)

Expr (create table): abc

```
