I've already read that the if statement in scala always returns an expression

So I'm trying to do the following (pseudo code)

```
sql = "select * from xx" + iif(order.isDefined, "order by " order.get, "")

```

I'm trying with

```
val sql: String = "select * from xx" + if (order.isDefined) {" order by " + order.get} else {""} 

```

But I get this error:

```
illegal start of simple expression

```

order is an Option[String]

I just want to have an optional parameter to a method, and if that parameter (in this case order) is not passed then just skip it

what would be the most idiomatic way to achieve what I'm trying to do?

-- edit --

I guess I hurried up too much to ask

I found this way,

```
val orderBy = order.map( " order by " + _ ).getOrElse("")

```

Is this the right way to do it?

I thought map was meant for other purposes...
