CDaoRecordset::Delete
Call this member function to delete the current record in an open dynaset-type or table-type recordset object.
virtual void Delete( );
Remarks
After a successful deletion, the recordset's field data members are set to a Null value, and you must explicitly call one of the recordset navigation member functions (Move, Seek, SetBookmark, and so on) in order to move off the deleted record. When you delete records from a recordset, there must be a current record in the recordset before you call Delete; otherwise, MFC throws an exception.
Delete removes the current record and makes it inaccessible. Although you cannot edit or use the deleted record, it remains current. Once you move to another record, however, you cannot make the deleted record current again.
Warning
The recordset must be updatable and there must be a valid record current in the recordset when you call Delete. For example, if you delete a record but do not scroll to a new record before you call Delete again, Delete throws a CDaoException.
You can undelete a record if you use transactions and you call the CDaoWorkspace::Rollback member function. If the base table is the primary table in a cascade delete relationship, deleting the current record may also delete one or more records in a foreign table. For more information, see the definition "cascade delete" in DAO Help.
Unlike AddNew and Edit, a call to Delete is not followed by a call to Update.
For related information, see the topics "AddNew Method", "Edit Method", "Delete Method", "Update Method", and "Updatable Property" in DAO Help.
