The table games shows the year and the city hosting the Olympic Games.

games yr city 2000 Sydney 2004 Athens 2008 Beijing 2012 London

schema:scott

 DROP TABLE games

 CREATE TABLE games(
  yr INTEGER,
  city VARCHAR(20));
INSERT INTO games VALUES (2000,'Sydney');
INSERT INTO games VALUES (2004,'Athens');
INSERT INTO games VALUES (2008,'Beijing');
INSERT INTO games VALUES (2012,'London');

The UPDATE statement can be used to change a values in rows that already exists. In this example we move the 2012 games from London to Paris.

UPDATE scott.games SET city='Paris' WHERE yr = 2012;
SELECT * FROM scott.games;

UPDATE games SET city='Paris' WHERE yr = 2012;
SELECT * FROM games;
