Instantiate a RecordsetCursor for this SortedRecordset (SortedRecordset class)
Syntax
%recordsetCursor = sortedRecordset:Cursor
Syntax terms
| %recordsetCursor | A declared RecordsetCursor object, to which Cursor returns an instance of a RecordsetCursor object, if sortedRecordset has at least one record. If sortedRecordset has no records, Cursor returns a Null object. |
|---|---|
| sortedRecordset | A reference to an instance of a SortedRecordset object. |
Usage notes
- You can have as many cursors as you want for a record set.
- To test for an empty record set, use IsEmpty, which is much more efficient than testing the record Count for 0.
- The instantiated RecordsetCursor is automatically positioned on the first record in the set.
