How To Select All Columns of All Rows from a Table with a SELECT statement?

The simplest query statement is the one that selects all columns of all rows from a single table: "SELECT * FROM tableName". The (*) in the SELECT clause tells the query to return all columns. The missing WHERE clause tells the query to return all rows in specified table. The tutorial exercise below returns all columns and all rows from table "fyi_links":

SELECT * FROM fyi_links
id    url                 notes   counts   created
101   dev.fyicenter.com   NULL    0        2006-04-30
102   dba.fyicenter.com   NULL    0        2007-05-19
103   sqa.fyicenter.com   NULL    NULL     2007-05-19
