SQL & PL/SQL :: Deleting Master / Detail Record?

I want to delete Master / Detail Data through cursor between date 01-02-2010 till 10-02-2010. Problem is in Detail I dont have date column in detail. But I have to delete Master and Detail record with desire date. I have made a cursor but it delete only detail record i want to delete master record too.

Master Table
M_NO CHAR (12) NOT NULL,
REMARKS VARCHAR2 (200),
CANCEL_YN CHAR (1) NOT NULL,
M_DATE DATE NOT NULL,
PRIMARY KEY ( M_NO ) ) ;

Detail Structure

M_SNO NUMBER NOT NULL,
ACCOUNT_CODE CHAR (19) NOT NULL,
CANCEL_YN CHAR (1) NOT NULL,
M_DESC VARCHAR2 (200),
DB_AMT NUMBER,
CR_AMT NUMBER,
M_NO CHAR (12) NOT NULL,
PRIMARY KEY ( M_SNO, M_NO ) ) ;

create or replace procedure test as
cursor md_cur is
select m_No from master where m_Date
between '01-02-2010' and '10-02-2010';
