Jumping to a Record

  • Άρθρο

The Move method allows you to move forward or backward in the Recordset a specified number of records by using the following syntax:

oRs.Move NumRecords, Start

Remarks

The Move method is supported on all Recordset objects.

If the NumRecords argument is greater than zero, the current record position moves forward (toward the end of the Recordset). If NumRecords is less than zero, the current record position moves backward (toward the beginning of the Recordset).

If the Move call would move the current record position to a point before the first record, 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 Move call would move the current record position to a point after the last record, 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.

Calling the Move method from an empty Recordset object generates an error.

If you pass a bookmark in the Start argument, the move is relative to the record with this bookmark, assuming the Recordset object supports bookmarks. A bookmark is obtained by using the Bookmark property. If not specified, the move is relative to the current record.

If you are using the CacheSize property to locally cache records from the provider, passing a NumRecords argument that moves the current record position outside the current group of cached records forces ADO to retrieve a new group of records, starting from the destination record. The CacheSize property determines the size of the newly retrieved group, and the destination record is the first record retrieved.
