sql - Flutter Drift(Moor)：连接两列

Question

我有一个表叫Contracts：

class Contracts extends Table {
  TextColumn get firstName => text().named('firstname')();

  TextColumn get lastName => text().named('lastname')();

  // some more columns
}

在View中，我想将两列连接到 SQL 中的一列：

firstname || ' ' || lastname as name

abstract class Bookings extends View {
  Contracts get c;
  @override
  Query as() => select([
    // firstname || ' ' || lastname as name, // what do I have to do here?
    // more stuff 
  ]).from(c);
}

但我找不到任何方法或类或其他任何方法。而且我在互联网上也没有找到任何例子。
