PL/SQL-Skript durch die Datensätze in einer Schleife, um alle Datensätze mit Zustand zu erhalten

Ich versuche, ein PL/SQL-Skript zu erstellen Anzahl der in einem Land auf der Grundlage dieser Bedingungen zu generieren:PL/SQL-Skript durch die Datensätze in einer Schleife, um alle Datensätze mit Zustand zu erhalten

Land
Natur Reise
Jahr
Dauer
- über 1 Monat
- Weniger als 1 Woche
- mehr als 1 Woche, aber weniger als 1 Monat

Das Endziel ist, so etwas zu bekommen (für 1 Jahr/1 Land):

Ich habe versucht, den manuellen Weg (dauert mich eine lange Zeit) der Generierung einzelner SQL-Anweisungen, aber ich bin mir nicht sicher, wie es über eine PL/SQL-Schleife zu tun. Schätze, wenn mir jemand zeigen kann, wie.

Unten ist die Tabellenstruktur in meiner Datenbank mit den relevanten Feldern.

Vielen Dank für jede Hilfe!

Könnten Sie einige Beispieldaten (zB auf pastebin.com) wie Skripte erstellen Datenbanken mit einigen Daten? Es könnte ohne PL/SQL gemacht werden und es würde nicht so viel Zeit brauchen. –

SQL

     a.nature_of_travel, 
     case d.rn 
     when 1 then 'More than 1 month' 
     when 2 then 'Less than 1 week' 
     else 'Between 1 week and 1 month' 
     end length_of_stay, 
     count(*) number_of_trips, 
     to_char(b.from_date,'YYYY') year 
    from TB_TRAVELITINERARY b 
    join TB_TRIP a on a.trip_id=b.trip_id 
    join TB_COUNTRY c on b.country_code= c.country_code 
    join (select rownum rn from dual connect by level < 4) d on 
    case when add_months(b.from_date,1) < b.to_date then 1 
      when b.from_date+7 > b.to_date then 2 
      else 3 
    end = d.rn

Danke Mottor .. Im so so so leid ... ich habe versehentlich einen Fehler auf meinen Tabellenspalten gemacht .. TB_TRAVEL_ITINERARY sollte die Spalte TRIP_ID haben und nicht umgekehrt. Das ist der Grund, egal wie ich den Code versuche, es funktioniert nicht. Wirklich schätzen Sie Ihre Hilfe aber .. Ich habe die Tabellen bereits aktualisiert. = X – user3188291

Ich habe es geändert – Mottor

Hallo Mottor, können Sie mir eine Beispielausgabe zur Verfügung stellen, wenn Sie Ihr Skript ausführen? Die Ausgabe, die ich vom Ausführen deines ersten Skripts bekomme, ist nur eine Liste von Ländernamen. :( – user3188291

Hier ein paar Alternativen - es hängt wirklich davon ab, wie Sie die Daten zurückgegeben werden sollen.

Dieses erste Beispiel gibt eine Zeile für jede Kombination von Jahr, Land und Art der Reise zurück, die in den Daten vorhanden ist. Mit den Daten habe ich verwende Es wird nicht eine Zeile für Australien und WORK geben, weil es keine Fahrten dieser Art:
