解決方法：
當(dāng)出現(xiàn)這個(gè)問題，說明 celive 配置文件中的數(shù)據(jù)庫與 cmseasy 的配置文件中數(shù)據(jù)庫不一致，修改方法為：
$config['database'] = '數(shù)據(jù)庫名稱';
$config['username'] = '數(shù)據(jù)庫用戶名';
$config['password'] = '數(shù)據(jù)庫用戶密碼';
$config['prefix'] = 'cmseasy_';
Table 'yuxin.cmseasy_activity' doesn't exist
DELETE FROM `cmseasy_activity` WHERE `id`=''
