Is this SortedRecordset empty? (SortedRecordset class)

IsEmpty returns a Boolean Enumeration whose value is True if the set is empty (has no records), and is False if the set has records.

Syntax

%boolean = sortedRecordset:IsEmpty

Syntax terms

%boolean An Enumeration object of type Boolean to contain the returned value of IsEmpty.
sortedRecordset A reference to an instance of a SortedRecordset object.

Usage Note

  • For convenience, use IsEmpty when you simply need to test for an empty set of records; it is more efficient as testing the record Count for 0. Use the Count property when you need the number of records.
