備註

DataAdapter 檢查每個插入、更新或刪除作業執行影響的資料列數目,如果數位等於零,則會擲回此例外狀況。The DataAdapter examines the number of rows affected by the execution of each insert, update, or delete operation, and throws this exception if the number equals zero. 這個例外狀況通常是由平行存取違規所造成。This exception is generally caused by a concurrency violation.
