ABOUT WAMP



           WAMPs are packages of independently-created programs installed on computers that use a Microsoft Windows operating system.

           WAMP is an acronym formed from the initials of the operating system Microsoft Windows and the principal components of the package:Apache, MySQL and one of PHP. Apache is a web server. MySQL is an open-source database. PHP is a scripting language that can manipulate information held in a database and generate web pages dynamically each time content is requested by a browser. Other programs may also be included in a package, such as phpMyAdmin which provides a graphical user interface for the MySQL database manager, or the alternative scripting languages Python or Perl. Equivalent packages are MAMP (for the Apple Mac) and LAMP (for the Linuxoperating system).

To find all countries that have the same year of independence as some given country, a self-join can be used. However, the query cannot be written like this: mysql> SELECT IndepYear, Name, Name -> FROM Country JOIN Country -> ON IndepYear = IndepYear AND Name = 'Qatar'; ERROR 1066 (42000): Not unique table/alias: 'Country' Furthermore, the ambiguity cannot be removed from column references by preceding them with table name qualifiers because the names remain identical: mysql> SELECT Country.IndepYear, Country.Name, Country.Name -> FROM Country JOIN Country -> ON Country.IndepYear = Country.IndepYear -> AND Country.Name = 'Qatar'; ERROR 1066 (42000): Not unique table/alias: 'Country' It ...
