MoveFirst, MoveLast, MoveNext, and MovePrevious Methods (ADO)

Moves to the first, last, next, or previous record in a specified Recordset object and makes that record the current record.


recordset.{MoveFirst | MoveLast | MoveNext | MovePrevious}

Use the MoveFirst method to move the current record position to the first record in the Recordset.

Use the MoveLast method to move the current record position to the last record in the Recordset. The Recordset object must support bookmarks or backward cursor movement; otherwise, the method call will generate an error.

A call to either MoveFirst or MoveLast when the Recordset is empty (both BOF and EOF are True) generates an error.

Use the MoveNext method to move the current record position one record forward (toward the bottom of the Recordset). If the last record is the current record and you call the MoveNext method, ADO sets the current record to the position after the last record in the Recordset (EOF is True). An attempt to move forward when the EOF property is already True generates an error.

In ADO 2.5 and later, when the Recordset has been filtered or sorted and the data of the current record is changed, calling the MoveNext method moves the cursor two records forward from the current record. This is because when the current record is changed, the next record becomes the new current record. Calling MoveNext after the change moves the cursor one record forward from the new current record. This is different from the behavior in ADO 2.1 and earlier. In these earlier versions, changing the data of a current record in the sorted or filtered Recordset does not change the position of the current record, and MoveNext moves the cursor to the next record immediately after the current record.

Use the MovePrevious method to move the current record position one record backward (toward the top of the Recordset). The Recordset object must support bookmarks or backward cursor movement; otherwise, the method call will generate an error. If the first record is the current record and you call the MovePrevious method, ADO sets the current record to the position before the first record in the Recordset (BOF is True). An attempt to move backward when the BOF property is already True generates an error. If the Recordset object does not support either bookmarks or backward cursor movement, the MovePrevious method will generate an error.

If the Recordset is forward only and you want to support both forward and backward scrolling, you can use the CacheSize property to create a record cache that will support backward cursor movement through the Move method. Because cached records are loaded into memory, you should avoid caching more records than is necessary. You can call the MoveFirst method in a forward-only Recordset object; doing so may cause the provider to re-execute the command that generated the Recordset object.
