jOOQ record mappers
Sometimes, we need a custom mapping that cannot be achieved via the fetchInto() method, the fetchMap() method, the fetchGroups() method, or the Records utility. A simple approach relies on Iterable.forEach(Consumer), as shown in the following mapping:
ctx.select(EMPLOYEE.FIRST_NAME,
           EMPLOYEE.LAST_NAME, EMPLOYEE.EMAIL)
   .from(EMPLOYEE)
   .forEach((Record3<String, String, String> record) -> {
      System.out.println("\n\nTo: "
       + record.getValue(EMPLOYEE.EMAIL));
      System.out.println("From: "
       + "hrdepartment@classicmodelcars.com");
      System.out.println("Body: \n   Dear, "
       + record...
