Is Recordset empty? (Recordset class)


This property 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.
