SYNOPSIS ^

    my $sql = DBIx::Skinny::SQL;
    $sql->select(['foo', 'bar', 'baz']);
    $sql->from(['table_name']);
    $sql->as_sql;
        #=> "SELECT foo, bar, baz FROM table_name;"

    $sql->add_where('col' => "value");
    $sql->as_sql;
        #=> "SELECT foo, bar, baz FROM table_name WHERE ( col = ? );"

    $sql->add_where(name => { like => "%value" });
    $sql->as_sql;
        #=> "SELECT foo, bar, baz FROM table_name WHERE ( col = ? ) AND ( name LIKE ? );"

    $sql->add_where(bar => \"IS NOT NULL");
    $sql->as_sql;
        #=> "SELECT foo, bar, baz FROM table_name WHERE ( col = ? ) AND ( name LIKE ? ) AND ( bar IS NOT NULL );"

    # execute SQL and return DBIx::Skinny::Iterator object.
    my $iter = $sql->retrieve;

    my $sql2 = DBIx::Skinny::SQL->new;
    $sql2->from([]);
    $sql2->add_join(foo => [
        { table => "bar", type => "inner", condition => "foo.bar_id = bar.id" },
    ]);
    $sql2->select(['*']);
    $sql2->as_sql;
        #=> "SELECT * FROM foo INNER JOIN bar ON foo.bar_id = bar.id;"

    $sql2->add_complex_where([[ -or => { foo => "bar" }, { foo => "baz" } ]]);
    $sql2->as_sql;
        #=> "SELECT * FROM foo INNER JOIN bar ON foo.bar_id = bar.id WHERE ( ( foo = ? ) OR ( foo = ? ) )"
