2000	Sydney
2004	Athens
2008	Beijing
2012	London

schema:scott

 DROP TABLE games

 CREATE TABLE games(
  yr INTEGER PRIMARY KEY,
  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 SELECT statement returns results from a table. The DELETE statement can be used to remove rows from a table. In this example we remove the 2000 games from the table:

DELETE FROM scott.games WHERE yr=2000;
SELECT * FROM scott.games;

DELETE FROM games WHERE yr=2000;
SELECT * FROM games;
