Example

The INSERT statement adds a new row to the table:

VALUES (2012,'London');
SELECT * FROM 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 games(yr,city) VALUES (2008,'Paris');
SELECT * FROM games;
