Batch API complains "No implicits found for parameter factory: Factory[Int, C_[Int]]"

[Sandeep Thandassery]

On using Batch API like below, apply method complains "No implicits found for parameter factory: Factory[Int, C_[Int]]". How can I get rid of this error? 

DBs.setupAll()

DB localTx { implicit session =>
  val batchParams: Seq[Seq[Any]] = (2001 to 3000).map(i => Seq(i, "name" + i))
  sql"insert into emp (id, name) values (?, ?)".batch(batchParams: _*).apply()
}

Thanks,

Sandeep

wrap it with a method that return a : List[Int]

or add the implicit 

implicit val intFactory = implicitly[Factory[Int, Seq[Int]]]
