As someone that answers a lot of SQL questions the best way In my opinion to include a table of data is as follows.
CREATE TABLE foo
Username varchar(20) PRIMARY KEY,
INSERT INTO foo
SELECT 'Username1','Password1','Email 1' UNION ALL
SELECT 'Username2','Password2','Email 2' UNION ALL
SELECT 'Username3','Password3','Email 3' UNION ALL
SELECT 'Username4','Password4','Email 4' UNION ALL
SELECT 'Username5','Password5','Email 5'
It gets tedious very quickly adding quotes onto strings, inserting commas and removing vertical bars, underscores and other such artefacts in order to set up a test table to answer the question.
