我有以下代码,它将行插入名为luczekInfo的表中,并使用函数从数据库中获取数据.我的问题是如何使函数更新表luczekInfo中的列,由get(id)函数返回的行.在Slick中更新列值的最佳方法是什么？

def create(profil: luczekInfo): Either[Failure, luczekInfo] = {
  try {
    val id = db.withSession {
      LuczekInfo returning LuczekInfo.id insert profil
    }
    Right(profil.copy(id = Some(id)))
  } catch {
    case e: SQLException =>
      Left(databaseError(e))
  }
}

def get(id: Int): Either[Failure, luczekInfo] = {
  try {
    db.withSession {
      LuczekInfo.findById(id).firstOption match {
        case Some(profil: luczekInfo) =>
          Right(profil)
            case _ =>
              Left(notFoundError(id))
      }
    }
  } catch {
    case e: SQLException =>
      Left(databaseError(e))
  }
}

提前感谢您的回答.

嗨,我是新的Scala,并有以下示例的问题:

import scala.slick.driver.MySQLDriver.simple._

    case class Customer(id: Option[Long], firstName: String, lastName: String, birthday: Option[java.util.Date])

/**
 * Mapped customers table object.
 */
object Customers extends Table[Customer]("customers") {

  def id = column[Long]("id", O.PrimaryKey, O.AutoInc)

  def firstName = column[String]("first_name")

  def lastName = column[String]("last_name")

  def birthday = column[java.util.Date]("birthday", O.Nullable)

  def * = id.? ~ firstName ~ lastName ~ birthday.? <>(Customer, Customer.unapply _)

  implicit val dateTypeMapper = MappedTypeMapper.base[java.util.Date, java.sql.Date](
  {
    ud => new java.sql.Date(ud.getTime)
  }, {
    sd => new java.util.Date(sd.getTime)
  })

  val findById = for { …
