插入后如何返回多个值? [英] How to return multiple values after insert?

问题描述

这是Slick 2.0.

It's Slick 2.0.

我有以下内容:

mytable
  .returning(mytable.map(_.id))
  .+=(item)(session)

我希望插入不仅返回id，而且返回name字段和lastname字段.可以在Slick中使用吗?

I'd like the insert not only to return the id but also the name field and the lastname fields. Is it possible in Slick?

推荐答案

map确定返回表的投影，因此您可以选择所需的字段并将它们打包在元组中.

map determines what projection of the table is returned, so you can pick the fields you need and pack them in a tuple:

mytable
  .returning(mytable.map(t => (t.id, t.name, t.lastname)))
  .+=(item)(session)
