MySQL 关键字和保留字通常在SQL语句中有特殊的意义，比如SELECT，DELETE，BIGINT等等，如果要使用这些关键字或者保留字作为表名、字段名，需要使用引号来标识，否则将会报错。
mysql> CREATE TABLE interval (begin INT, end INT);
ERROR 1064 (42000): You have an error in your SQL syntax ... near 'interval (begin INT, end INT)'
mysql> CREATE TABLE `interval` (begin INT, end INT);
Query OK, 0 rows affected (0.01 sec)
