Table Properties


MySQL manages tables using storage engines, each of which handles tables that have a given set of characteristics. Different storage engines have differing performance characteristics, and can be chosen based on which engine most closely matches the char acteristics that are needed. For example, a table may require transactional capabilities and guaranteed data in tegrity even if a crash occurs, or it may require a very fast lookup table stored in memory for which the contents can be lost in a crash and reloaded at the next server startup.  With MySQL, these choices can be made on a per-table basis. Any given table is managed by a particular storage engine.

Options can be added to the CREATE TABLE  command in order to control the manner in which the entire table is handled.


ENGINE={MyISAM | InnoDB | MEMORY}
  •   Indicates the storage engine to be used for the table
  •  MyISAM is the default storage engine (unless --default-storage-engine has been set)

COMMENT='<comment>'  

  •  Up to 60 characters of free form text  

CHARACTER SET=<character set> 

  • Specifies the character set for the table 
  •   Precede with DEFAULT to assign the default character set
  • Can be shortened to CHARSET  

COLLATE= <collation_name>
  • Specifies the collation for the table
  •  Precede with DEFAULT  to assign the default collation

PHP INTRODUCTION

                     PHP  (recursive acronym for  PHP: Hypertext Preprocessor ) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML. PHP stands for  P HP:  H ypertext  P reprocessor PHP is a server-side scripting language, like ASP PHP scripts are executed on the server PHP supports many databases (MySQL, Informix, Oracle, Sybase, Solid, PostgreSQL, Generic ODBC, etc.) PHP is an open source software PHP is free to download and use Why PHP? PHP runs on different platforms (Windows, Linux, Unix, etc.) PHP is compatible with almost all servers used today (Apache, IIS, etc.) PHP is FREE to download from the official PHP resource:  www.php.net PHP is easy to learn and runs efficiently on the server side What can PHP do? Anything. PHP is mainly focused on server-side scripting, so you can do anything any other CGI program can do, such as collect form data, generate dynam

MySQL General Architecture

        MySQL operates in a networked environment using a client/server architecture. In other words, a central  program acts as a server, and various client programs connect to the server to make requests. A MySQL  installation has the following major components: MySQL Server, Client programs and MySQL non client  utilities.  MySQL Server MySQL Server, or mysqld, is the database server program. The server manages access to the actual  database (schema) on disk and in memory. MySQL Server is multi-threaded and supports many  simultaneous client connections. Clients can connect via several connection protocols. For managing  database contents, the MySQL server features a modular architecture that supports multiple storage engines  that handle different types of tables (for example, it supports both transactional and non-transactional  tables). Keep in mind the difference between a server and a host. The server is software (the MySQL server  program mysqld). Server characteristi
