　　前期工作

my.cnf

max_heap_table_size = 128M

　　建表

use test;---- Store engine heap--CREATE TABLE `tbl_heap` ( `id` int(11) NOT NULL auto_increment, `name` varchar(32) NOT NULL default '', `email` varchar(32) NOT NULL default '', `summary` varchar(255) default '', KEY `id` (`id`) ) ENGINE=HEAP DEFAULT CHARSET=gbk; ---- Store engine myisam--CREATE TABLE `tbl_isam` ( `id` int(11) NOT NULL auto_increment, `name` varchar(32) NOT NULL default '', `email` varchar(32) NOT NULL default '', `summary` varchar(255) default '', KEY `id` (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=gbk;
