RowParser for Optional Long

[krjackso]

I was doing a query like this:

sql"""SELECT SUM(x) as c FROM table WHERE ...""".as[Option[Long]]

and trying to parse with this

implicit val sumParser: RowParser[Long] = RowParser(RowParser.long("c"))

It works fine until SUM(x) is NULL which happens when there are no rows (due to where clause). I get this exception:

Caused by: java.util.NoSuchElementException: None.get
	at scala.None$.get(Option.scala:347)
	at scala.None$.get(Option.scala:345)

	at com.lucidchart.relate.SqlRow.withResultSet(SqlRow.scala:16)

I was able to work around it by changing my query but it should be fixed:
sql"""SELECT COALESCE(SUM(x), 0) as c FROM table WHERE ...""".as[Option[Long]]
