Initializing Records
The illustration below shows that you can initialize a record in its type definition. Whenever you declare a record of the type TimeRec, its 3 fields suppose an initial value of zero.
DECLARE
TYPE TimeRec IS RECORD (
secs SMALLINT := 0,
mins SMALLINT := 0,
hrs SMALLINT := 0);

TYPE StockItem IS RECORD (
item_no INTEGER(3) NOT NULL := 999,
description VARCHAR2(50),
quantity INTEGER,
price REAL(7,2));
