錯誤信息：
錯誤語句：create database 'mmall' default character set utf8 collate utf8_general_ci;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''mmall' default character set utf8 collate utf8_general_ci' at line 1
原因：
語句本身沒毛病，是語法上的錯誤，在MySQL中，爲了區分MySQL的關鍵字與普通字符，MySQL引入了一個反引號。蛋疼啊，反引號：（`）
