Ich habe eine Reihe von Zeilen in meiner Datenbank, die so aussehen:

Mr Joe Bloggs
Joe Bloggs
Joe Jim Bloggs
Joe Jim David Bloggs
Mr Joe Jim Bloggs
Mr Joe Jim David Bloggs

Ausgabe erforderlich:

Title | First Name | Middle Name | Surname
------------------------------------------
Mr | Joe | x | Bloggs
x | Joe | x | Bloggs
x | Joe | Jim | Bloggs
x | Joe | Jim David | Bloggs
Mr | Joe | Jim | Bloggs
Mr | Joe | Jim David | Bloggs

Dies wird in einer gespeicherten SQL-Prozedur ausgeführt. Was ich brauche, ist diese Ausgabe, die beim Durchlaufen eines CURSOR und der 4 Variablen erzeugt wird, um die 4 Spalten in der Datenbank zu aktualisieren. Wie Sie jedoch sehen können, befinden sich die Daten in einer Spalte und variieren.

Ich finde es schwer zu verstehen, wie das am besten funktioniert, und bitte um Ihre Hilfe. Lassen Sie mich wissen, wenn Sie noch etwas brauchen.

Ähnliche Fragen zu meinen, aber ich glaube, diese geben mir nicht die vollständige Antwort, die ich brauche, oder ich denke, dass sie meine Frage nicht beantworten:
