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:

DECLARE

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);
