DROP TABLE schedule;
CREATE TABLE schedule (week
NUMBER,
Mon VARCHAR2(10),
Tue VARCHAR2(10),
Wed VARCHAR2(10),
Thu VARCHAR2(10),
Fri VARCHAR2(10),
Sat VARCHAR2(10),
Sun VARCHAR2(10));
DECLARE
default_week
schedule%ROWTYPE;
i NUMBER;
BEGIN
default_week.Mon :=
'0800-1700';
default_week.Tue :=
'0800-1700';
default_week.Wed :=
'0800-1700';
default_week.Thu := '0800-1700';
default_week.Fri :=
'0800-1700';
default_week.Sat := 'Day
Off';
default_week.Sun := 'Day
Off';
FOR i IN 1..6 LOOP
default_week.week := i;
INSERT
INTO schedule VALUES default_week;
END LOOP;
END;
