View Source Request Example

    function QueryRecordsAsync(restriction, cancellationToken);

#### Parameters

restriction RecordRestriction
  Record restriction to apply.
cancellationToken CancellationToken
  Propagates notification that operations should be canceled.

#### Return Value

IAsyncEnumerable T
An enumerable of modeled table row instances for queried records.

## Remarks

This is a convenience call to QueryRecords(String, RecordRestriction, Int32) only specifying the RecordRestriction parameter.

If any of the restriction parameters reference a table field that is modeled with either an EncryptDataAttribute or FieldDataTypeAttribute, then the function GetInterpretedFieldValue(String, Object) will need to be called, replacing the target parameter with the returned value so that the field value will be properly set prior to executing the database function.
