CRecordset::MovePrev

void MovePrev( );
throw( CDBException, CMemoryException );

Remarks

Call this member function to make the first record in the previous rowset the current record. If you have not implemented bulk row fetching, your recordset has a rowset size of 1, so MovePrev simply moves to the previous record.

Note This member function is not valid for forward-only recordsets.

Note When moving through a recordset, deleted records may not be skipped. See the IsDeleted member function for details.

Caution Calling any of the Move functions throws an exception if the recordset has no records. To determine whether the recordset has any records, call IsBOF and IsEOF.

It is also recommended that you call IsBOF before calling MovePrev. For example, if you have scrolled ahead of the beginning of the recordset, IsBOF will return nonzero; a subsequent call to MovePrev would throw an exception.

If you call any of the Move functions while the current record is being updated or added, the updates are lost without warning.
