Oracle Database Interview Question:

How To Retrieve Values from Data Fields in RECORD Variables?

Submitted by: Administrator

If a variable is a RECORD variable with data fields assigned values, you can retrieve those values out of its data fields by using fields names prefixed with variable name as "variable.field_name". Here is a sample script showing you how to retrieve field values from RECORD variables:

CREATE OR REPLACE PROCEDURE HELLO AS
TYPE student IS RECORD (
id NUMBER(5),
first_name VARCHAR(80),
last_name VARCHAR(80)
);
best_student student;
another_student student;
class_name VARCHAR2(80);
BEGIN
class_name := 'ggl Center 2006';
best_student.first_name := 'The';
best_student.last_name := 'Best';
DBMS_OUTPUT.PUT_LINE('Best student = ' ||
best_student.first_name || ' '
|| best_student.last_name);
END;
/
Best student = The Best
