Error while executing SQL query in Play Framework

Question

I'h getting problems with executing SQL query in Play 2.3 application and h2-memory db.

code where is a problem:

DB.withConnection { implicit c =>
Sql("").executeInsert()
}

Error(in InteliJ Sql is red marked)

anorm.Sql.type does not take parameters

Any ideas?

Whole class:

import play.api.Play.current
import play.api.db.DB
import anorm._

case class User(username: String, password: String) {

def save() = {
  DB.withConnection { implicit c =>
    SQL("").executeInsert()
  }
}
}
