Consecutive mappings

[KuceraMartin]

How to translate this?

from(table).map{ t => (t.firstName, t.age.as("a")) }
  .sortBy(_.a)
  .map(_.firstName)

Solutions:

• Select age AS a even though it's mapped out.
• Transform order-by to inner expression (without alias) -- potentially recursively.
• Translate consecutive mappings using subqueries.

  • 
    SELECT s.first_name
    FROM (
    SELECT first_name, age AS a
    FROM table
    ORDER BY a
    ) s

subqueries sound good

[KuceraMartin]

can we compare case classes by reference equality?

eq
