Azure SQL-Datenbank-Abfrage

Question

ich eine Datenbank auf Azure erstellt habe Ich bin auch in der Lage Azure SQL-Datenbank von meinem lokalen Server zugreifen, indem

Firewall usw. Einstellung

Was ich merke, wenn ich eine Tabelle Schemaänderung tun zB erstellen neue Tabelle oder fügen Sie eine neue Spalte zu einer vorhandenen Tabelle hinzu, die Änderungen spiegeln die Azure App nicht wider (obwohl ich die letzten Tabellenänderungen in Azure SQL-Datenbank-Abfrageeditor sehen kann)

Ich habe versucht, TODO-Beispielanwendung zu ändern, die Azure bereitstellt mit einer Standard-TODO-Tabelle.

Nachdem die App von Azure heruntergeladen und ausgeführt wurde, wird App ohne Probleme ausgeführt, indem die richtigen Daten aus der TODO-Tabelle geladen werden.

Aber wenn ich eine neue Spalte/Umbenennung Spalte der vorhandenen TODO-Tabelle hinzufügen, ändert DOT-Datei, um neue Spalte in API-Dienst hinzuzufügen und veröffentlichte den Dienst. APP stoppt Daten mit Verbindungsfehler ...

Basierend auf der Fehlermeldung verwenden Sie das C# -Backend für Ihre Azure Mobile Apps. Um eine neue Tabelle hinzuzufügen, müssen Sie das Modell Ihrer Tabelle definieren und einen Table Controller dafür erstellen. Um die Spalte (n) zu bearbeiten, könnten Sie das Tabellenmodell bearbeiten. Bevor Sie das Backend auf Azure veröffentlichen, müssen Sie Code-Erstmigrationen implementieren. Sie können die Migrationsdatei manuell über add-migration erstellen und den Befehl update-database anwenden, um die vorhandene Migration anzuwenden. Außerdem können Sie die automatischen ersten Migrationen des Codes aktivieren. Weitere Details finden Sie in Adrian Halls Buch Implementing Table Controllers. Moverover können Sie auch Handling Publish Failures überprüfen.
