#[macro_use] extern crate sql_builder;
use sql_builder::{SqlBuilder, SqlName};

let sql = SqlBuilder::select_from(name!("public", "BOOKS"; "b"))
    .field(name!("b", "title"))

    .left()
    .join(name!("shops"; "s"))
    .on_eq(name!("b", "id"), name!("s", "book"))
    .sql()?;

assert_eq!("SELECT b.title, s.total FROM `public`.`BOOKS` AS b LEFT JOIN shops AS s ON b.id = s.book;", &sql);
