# errorNoData

Data is unavailable for the requested query and predicate.

## Declaration

```swift
static var errorNoData: HKError.Code { get }
```

## Discussion

Discussion This error indicates that no data exists that corresponds to a particular query, so the system can’t calculate the query’s result. HKStatisticsQuery queries return this error when HealthKit can’t return the data needed to calculate the statistics.
