如何使用 Slick Lifted Embedding 更新多个列? [英] How do you update multiple columns using Slick Lifted Embedding?

问题描述

如何使用 Slick Lifted Embedding 更新多个列?本文档不多说了.

How do you update multiple columns using Slick Lifted Embedding ? This document doesn't say much.

我希望它是这样的

Query(AbilitiesTable).filter((ab: AbilitiesTable.type) => ab.id === ability_id).map((ab: AbilitiesTable.type) => (ab.verb, ab.subject)).update("edit", "doc")

推荐答案

我想通了.应该是这样的

I figured it out. It should be like this

val map = Query(AbilitiesTable)
  .filter(_.id === ability_id)
  .map(ab => ab.verb ~ ab.context)

map.update(("", ""))
