# Delete Many

Database.

**Collections** hold your records. Norbix generates a full CRUD + query API over each collection from its schema, with record-level ownership and triggers.

This endpoint removes the many. This action cannot be undone.

{% hint style="warning" %}
This action is destructive or irreversible. Make sure you target the right item and confirm before running it.

## Empty filter

An empty filter `{}` (or no filter) is refused with `CM-ERRORS-DATABASE-037` so that a missing filter cannot touch the whole collection. To delete every record on purpose, send `allRecords: true` together with the empty filter. Soft-deleted records are skipped. A caller with only own-record rights (`deleteOwn`) may call it too — the filter is narrowed to records the caller owns.

## Refused operators

A filter (or pipeline) that contains `$where`, `$function` or `$accumulator` — the MongoDB operators that run JavaScript on the database server — is refused with `CM-ERRORS-DATABASE-031` (*Operator '…' is not allowed in a record filter or read-only aggregation pipeline.*), one error per operator, at any depth. Use ordinary query operators instead.

## Use it from code

Every Norbix SDK exposes this endpoint as a method — see [Delete Many](/codemash/sdks/database/collections/delete-many.md) in the SDK reference, with examples in every language.
