Examples

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

let sql = SqlBuilder::select_from(brname!("public", "BOOKS"; "b"))
    .field(brname!("b", "title"))
    .field(brname!("s", "total"))
    .left()
    .join(brname!("shops"; "s"))
    .on_eq(brname!("b", "id"), brname!("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);
