mysql - mysql一定要格式化才能进入吗？

Question

这真的超级奇怪，也许有人知道答案，

我有一张这样的桌子

mysql> describe sweeps;
+----------------+------------------+------+-----+---------------------+-----------------------------+
| Field          | Type             | Null | Key | Default             | Extra                       |
+----------------+------------------+------+-----+---------------------+-----------------------------+
| entity_id      | int(20) unsigned | NO   | PRI | NULL                | auto_increment              |
| fb_id          | varchar(120)     | YES  |     | NULL                |                             |
| title          | varchar(5)       | YES  |     | NULL                |                             |
| first_name     | varchar(30)      | YES  |     | NULL                |                             |
| last_name      | varchar(30)      | YES  |     | NULL                |                             |
| birthday_month | int(2) unsigned  | YES  |     | NULL                |                             |
| birthday_day   | int(2) unsigned  | YES  |     | NULL                |                             |
| birthday_year  | int(4) unsigned  | YES  |     | NULL                |                             |
| created_at     | datetime         | YES  |     | 0000-00-00 00:00:00 |                             |
| last_submit    | timestamp        | NO   |     | CURRENT_TIMESTAMP   | on update CURRENT_TIMESTAMP |
+----------------+------------------+------+-----+---------------------+-----------------------------+

INSERT如果我像这样把它放在一行中，那将不接受

mysql> `sweeps` (entity_id,fb_id,title,first_name,last_name,birthday_month,birthday_day,birthday_year,created_at) VALUES (1,'fooID1','mr','John','Doe',1,1,1999,NOW());
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 '`sweeps` (entity_id,fb_id,title,first_name,last_name,birthday_month,birthday_day' at line 1

但奇怪的是，如果我像这样隔开它，它会毫无错误地接受它吗？为什么是这样？

mysql> INSERT INTO `sweeps` (
    ->   entity_id,
    ->   fb_id,
    ->   title,
    ->   first_name,
    ->   last_name,
    ->   birthday_month,
    ->   birthday_day,
    ->   birthday_year,
    ->   created_at
    -> ) VALUES (
    ->   1,
    ->   'fooID1',
    ->   'mr',
    ->   'John',
    ->   'Doe',
    ->   1,
    ->   1,
    ->   1999,
    ->   NOW()
    -> );
Query OK, 1 row affected (0.41 sec)

mysql> SELECT * FROM sweeps;
+-----------+--------+-------+------------+-----------+----------------+--------------+---------------+---------------------+---------------------+
| entity_id | fb_id  | title | first_name | last_name | birthday_month | birthday_day | birthday_year | created_at          | last_submit         |

Answer 1

它不会插入，因为您INSERT INTO在命令中缺少：

mysql> `sweeps` (entity_id,fb_id,title,first_name,last_name,...

应该

mysql> INSERT INTO `sweeps` (entity_id,fb_id,title,first_name,last_name,...

Answer 2

你有一个“插入”

您的示例中缺少：

mysql> `sweeps` (entity_id,
