SQL lexer

Build Status Crate

Rust library to lex and sanitize SQL. To lex a query and write back to a string:

extern crate sql_lexer;

fn main() {
  let sql = sql_lexer::lex("SELECT * FROM `table`".to_string()).lex();
  println!("{}", sql_lexer::write(sql));

To sanitize all content from a query so you just get the generic components:

extern crate sql_lexer;

fn main() {
  println!("{}", sql_lexer::sanitize_string("SELECT * FROM `table` WHERE id = 1".to_string()));

This will output:

SELECT * FROM `table` WHERE id = ?

The documentation is available here.

Command line

There's a utility included to sanitize a sql query in a file to facilitate testing:

cargo run -- <path-to-file>
