1,在config配置文件中增加数据库配置:
'DB_TBANK'=>array(
'db_type' => 'mysql',
'db_host' => 'IP地址',
'db_user' => 'root',
'db_pwd' => '123456',
'db_name' => '数据库名称',
'db_port' => '3306',
'db_charset' => 'utf8',
//'DB_PREFIX' => 't_', // 数据库表前缀
),
2,在用户MODEL中定义:
protected $tablePrefix = 't_';
protected $connection = "DB_TBANK";

运行后出现:


没有定义数据库配置
