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
| %bool | A declared enumeration object of type Boolean to contain the returned value of IsEmpty. |
|---|---|
| %srecs | 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.
