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);
The illustration later shows that you can impose the NOT NULL constraint on any field, and so avoid the assigning of nulls to that field. The Fields declared as NOT NULL should be initialized.
TYPE StockItem IS RECORD (
item_no INTEGER(3) NOT NULL := 999,
description VARCHAR2(50),
quantity INTEGER,
price REAL(7,2));
