# sectionIdentifier

The request’s section identifier key path.

```
var sectionIdentifier: KeyPath<Result, SectionIdentifier>
```

## Discussion

Set this configuration value to cause a [`SectionedFetchRequest`](/documentation/SwiftUI/SectionedFetchRequest)
to execute a fetch with a new section identifier. You can’t change
the section identifier type without creating a new fetch request.
Use care to coordinate section and sort updates, as described
in [`SectionedFetchRequest.Configuration`](/documentation/SwiftUI/SectionedFetchRequest/Configuration).

Access this value for a given request by using the
[`sectionIdentifier`](/documentation/SwiftUI/SectionedFetchResults/sectionIdentifier) property on the
associated [`SectionedFetchResults`](/documentation/SwiftUI/SectionedFetchResults) instance, either directly or
with a [`Binding`](/documentation/SwiftUI/Binding).
