Scala Anorm select 2 values using column resolution

Question

According to documentation ( https://www.playframework.com/documentation/2.5.x/Anorm ), I can do the following to retrieve values from 2 columns:

val res: (String, Int) = SQL"SELECT text, count AS i".map(row =>
  row[String]("text") -> row[Int]("i")
)

This does not compile...

Causes this:

Expression of type SimpleSql[(String, Int)] doesn't conform to expected type (String, Int)

I'm just looking for a single method of doing this (for anorm 2.5+). I was using regular parsers but am looking for this more concise way of doing it.

Answer 1

The code is not complete: to get a single result as such tuple, the .single combinator must be used.

val res: (String, Int) = SQL"SELECT text, count AS i".map(row =>
  row[String]("text") -> row[Int]("i")
).single

Using Anorm flatteners is easier for tuple result: see examples
