case class Select(input: Query, projections: Option[Vector[SelectProjection]] = None, selection: Vector[Condition] = Vector.empty) extends Query with Product with Serializable
A Select selects elements from a stream of tabular rows. (Like in SQL Selects), transforms and filters them
Mantik only supports a subset of SQL Selects yet, however it's a design goal that improvements should be solved similar to SQL if applicable.
