CRecordset::MovePrev
Makes the first record in the previous rowset the current record.
void MovePrev( );
Remarks
If you have not implemented bulk row fetching, your recordset has a rowset size of 1, so MovePrev simply moves to the previous record.
Hinweis
This member function is not valid for forward-only recordsets.
Hinweis
When you move through a recordset, you cannot skip deleted records. See the IsDeleted member function for details.
Warnung
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.
Hinweis
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.
Hinweis
If you call any of the Move functions while the current record is being updated or added, the updates are lost without warning.
For more information about recordset navigation, see the articles Recordset: Scrolling (ODBC) and Recordset: Bookmarks and Absolute Positions (ODBC). For more information about bulk row fetching, see the article Recordset: Fetching Records in Bulk (ODBC).
Exceptions
This method can throw exceptions of type CDBException* and CMemoryException*.
Example
See the example for IsBOF.
