Missing comma to a query in chapter 9

[rednafi]

There's a syntax error in this query:

FOR n IN {1, 2, 3, 4, 5}
UNION (
  INSERT Crewman {
    number := n
    first_appearance := cal::to_local_date(1887, 7, 6),
    last_appearance := cal::to_local_date(1887, 7, 16),
  }
);

A comma is required in line 4 to fix the syntax error:

FOR n IN {1, 2, 3, 4, 5}
UNION (
  INSERT Crewman {
    number := n,
    first_appearance := cal::to_local_date(1887, 7, 6),
    last_appearance := cal::to_local_date(1887, 7, 16),
  }
);
