      SQL("Select VehicleJourneyUID,VehiclePositionLattitude,VehiclePositionLongitude 
        from csv_output where  VehicleJourneyUID in (31356)")().map{ row=>
        Contact(
          id=row[String]("VehicleJourneyUID"),
          VehiclePositionLattitude=row[Double]("VehiclePositionLattitude"),
          VehiclePositionLongitude=row[Float]("VehiclePositionLongitude")
        )
      }.toList

    } 
  }

Answer 1

Did you try to use implicit Reads and Writes for Float? or how about validate it with BigDecimal data type even it appears as Float at SQL Database.

Hope it helps.
