#35419: Add support for creating records from a queryset -------------------------------------+------------------------------------- Reporter: c-w | Owner: nobody Type: New | Status: new feature | Component: Database | Version: layer (models, ORM) | Severity: Normal | Keywords: Triage Stage: | Has patch: 0 Unreviewed | Needs documentation: 0 | Needs tests: 0 Patch needs improvement: 0 | Easy pickings: 0 UI/UX: 0 | -------------------------------------+------------------------------------- For performing efficient inserts based on existing data, it would be great if Django could offer support for the ANSI SQL **INSERT INTO ... SELECT FROM ...**, perhaps something along the lines of the following snippet:
{{{ queryset = MyTable.objects.filter(field=value) MyTable.objects.create_from(queryset) }}} Currently this type of insertion is only possible by bypassing the ORM or by evaluating the queryset and then doing a bulk_create. The former is undesirable for maintainability and the latter is inefficient as it executes 2 queries and potentially transfers a lot of data over the network. The feature has been requested in a few other places such as [https://stackoverflow.com/questions/70888534/ StackOverflow] and the [https://forum.djangoproject.com/t/14648/ Django Forum] so I figured that it would be a good idea to open an actual ticket for it. If the feature request were to be accepted, I can work on a patch for it if provided with some high-level guidance. -- Ticket URL: <https://code.djangoproject.com/ticket/35419> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
