How To Create a New Table Using the MEMORY Storage Engine?

MEMORY storage engine stores table data in computer system memory. This is good for creating temporary tables.

MEMORY is not the default storage engine. You need to specify "ENGINE = MEMORY" at the end of the "CREATE TABLE" statement to create new tables with the MEMORY storage engine. The tutorial exercise below shows you a good example:

>cd \mysql\bin
>mysql -u dev -piyf fyi

mysql> CREATE TABLE fyi_memory (
  id INTEGER PRIMARY KEY,
  title VARCHAR(80), 
  count INTEGER )
  ENGINE = MEMORY;
Query OK, 0 rows affected, 1 warning (0.07 sec)

mysql> SHOW CREATE TABLE fyi_memory;
  CREATE TABLE `fyi_memory` (
  `id` int(11) NOT NULL,
  `title` varchar(80) default NULL,
  `count` int(11) default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MEMORY DEFAULT CHARSET=latin1 
1 row in set (0.02 sec)
