schema:scott

 DROP TABLE games

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

The INSERT statement adds a new row to the table:

INSERT INTO scott.games(yr,city) 
VALUES (2012,'London');
SELECT * FROM scott.games;

INSERT INTO games(yr,city) 
VALUES (2012,'London');
SELECT * FROM games;

What can go wrong

Your INSERT statement may break some database rule such as the unique key requirement. In this example there is a primary key on year - that means that there may not be two rows with the same year. If you attempt to add a second row with 2008 for yr then you will get an error.

INSERT INTO scott.games(yr,city) 
VALUES (2008,'Paris');
SELECT * FROM scott.games;

INSERT INTO games(yr,city) 
VALUES (2008,'Paris');
SELECT * FROM games;
