初始化数据库适配器

db);
		 $db->query('SET  NAMES  UTF8');
		 Zend_Db_Table::setDefaultAdapter($db);
	}
}
?>

对应数据库中的course表，其中主键为cid

对应数据库中student表，其中主键为sid

数据库配置：

[production]
phpSettings.display_startup_errors = 0
phpSettings.display_errors = 0
includePaths.library = APPLICATION_PATH "/../library"
bootstrap.path = APPLICATION_PATH "/Bootstrap.php"
bootstrap.class = "Bootstrap"
appnamespace = "Application"
resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers"
resources.frontController.params.displayExceptions = 0

[mysql]
db.adapter=PDO_MYSQL
db.params.host=localhost
db.params.username=root
db.params.password=root
db.params.dbname=stusys

student表的创建

create table student(
sid char(8) primary key,
sname varchar(64) not null default '',
ssex char(2) not null defalut '女',
sdept varchar(32) not null default '',
sage tinyint unsigned default 0,
saddress varchar(64) not null default '');

course表的创建

create table course(
cid char(2) primary key,
cname varchar(64) not null default '',
ccredit tinyint unsigned not null default 0);
