Declaring Records
Whenever you define a RECORD type, you may declare records of that type, as the illustration shows:
DECLARE
TYPE StockItem IS RECORD (
item_no INTEGER(3),
description VARCHAR2(50),
quantity INTEGER,
price REAL(7,2));
item_info StckItem; -- declare record

PROCEDURE raise_salary (emp_info EmpRec);
