Oracle Database Interview Question:

How To Define a RECORD Variable to Store a Table Row?

Submitted by: Administrator

If you have a table, and want to define a RECORD variable to store all the data elements of a row from that table, you can use table_name%ROWTYPE to define the RECORD variable as shown in the following sample script:

CREATE TABLE student (id NUMBER(5) PRIMARY KEY,
first_name VARCHAR(80) NOT NULL,
last_name VARCHAR(80) NOT NULL);
Table created.

CREATE OR REPLACE PROCEDURE ggl_CENTER AS
best_student student%ROWTYPE;
another_student student%ROWTYPE;
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 ID = '
|| best_student.id);
DBMS_OUTPUT.PUT_LINE('Best student = ' ||
best_student.first_name || ' '
|| best_student.last_name);
END;
/
Best student ID =
Best student = The Best
