在application->config->database.php中，如下设置prefix

'mysql' => array(
'driver'   => 'mysql',
'host'     => 'localhost',
'database' => 'foodb',
'username' => 'root',
'password' => '',
'charset'  => 'utf8',
'prefix'   => 'ula_',       <-- this is where you need to set the table prefix
),

设置后，再次migrate:reset和migrate 我已经做到了，它的作品很完美

After setting this, migrate:reset and migrate it again I have done this way and its works perfect
