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
The identifier item_info represents the whole record.
Like the scalar variables, the user-defined records can be declared as the formal parameters of the procedures and functions. An illustration is as shown:
TYPE EmpRec IS RECORD (
emp_id emp.empno%TYPE,
last_name VARCHAR2(10),
job_title VARCHAR2(15),
salary NUMBER(7,2));
...
PROCEDURE raise_salary (emp_info EmpRec);
