Updating Row in Slick 3.0.0-RC3, using

This is how I update a row of table using Slick 2.1,

private def updateEntity(id: Long, row: TTable#TableElementType) = {
        db.withSession { implicit session =>
          val result = query.filter(_.id === id).update(row)             
          result.toLong
        }
      }

After I upgrade to Reactive Slick, db.withSession showing deprecation warning as withSession deprecated. what is the Action-based api syntax for updating a row.

Slick 3.0 uses pure functional, monadic I/O without side effects. In Action based API, you will have to use db.run which will take the Query and return a Future.

So in your case, it will be 

private def updateEntity(id: Long, row: TTable#TableElementType): Future[Long] = {
    db.run(query.filter(_.id === id).update(row)).map(_.toLong)
    }
  }
