Is Recordset empty? (Recordset class)
IsEmpty returns a "Boolean Enumeration" whose value is True if the set is empty (has no records) and False if the set has records.
Syntax
%boolean = recordset:IsEmpty
Syntax terms
| %boolean | A declared enumeration object of type Boolean to contain the returned value of IsEmpty. |
|---|---|
| recordset | An instantiated Recordset object variable. |
Usage notes
- Since it is much more efficient than testing the record count for 0, use IsEmpty when you simply need to test for an empty set. Use Count only when you need the number of records.
