Question

我正在使用MySQL Workbench来创建和管理漫画书商店数据库。我在向COMIC_ISSUE表中插入行时遇到问题。我遇到的问题是同样的问题，许多其他人在这里发布的问题只是没有一个修复似乎对我有用。以下是有关COMIC_TITLE和COMIC_ISSUE表的信息。我列出了COMIC_TITLE表，因为'name'列是COMIC_ISSUE中复合主键的一部分。

mysql> describe comic_title;
 +-------------------+-------------+------+-----+---------+-------+
 | Field             | Type        | Null | Key | Default | Extra |
 +-------------------+-------------+------+-----+---------+-------+
 | name              | varchar(45) | NO   | PRI | NULL    |       |
 | CREATOR_creatorID | int(11)     | NO   | PRI | NULL    |       |
 | isActive          | tinyint(1)  | NO   |     | 1       |       |
 +-------------------+-------------+------+-----+---------+-------+
 3 rows in set (0.01 sec)

mysql> select * from comic_title;
+----------+-------------------+----------+
| name     | CREATOR_creatorID | isActive |
+----------+-------------------+----------+
| Avengers |                 1 |        1 |
| Batman   |                 2 |        1 |
| Ironman  |                 3 |        1 |
+----------+-------------------+----------+
3 rows in set (0.00 sec)

mysql> describe comic_issue;
+-----------------------+--------------+------+-----+---------+-------+
| Field                 | Type         | Null | Key | Default | Extra |
+-----------------------+--------------+------+-----+---------+-------+
| COMIC_TITLE_name      | varchar(45)  | NO   | PRI | NULL    |       |
| volumeNum             | int(11)      | NO   | PRI | NULL    |       |
| coverDate             | date         | NO   | PRI | NULL    |       |
| PUBLISHER_publisherID | int(11)      | NO   | MUL | NULL    |       |
| inventoryQty          | int(11)      | NO   |     | NULL    |       |
| coverPrice            | decimal(4,2) | NO   |     | NULL    |       |
| issueTitle            | varchar(45)  | YES  |     | NULL    |       |
| synopsis              | longtext     | YES  |     | NULL    |       |
| format                | varchar(45)  | YES  |     | NULL    |       |
| storyArc              | varchar(45)  | YES  |     | NULL    |       |
+-----------------------+--------------+------+-----+---------+-------+
10 rows in set (0.00 sec)

以下是我尝试过的一些INSERT：

mysql> INSERT INTO `cbdb`.`COMIC_ISSUE` VALUES ('Batman', 1, '2011-11-01', (SELECT PublisherID from PUBLISHER where name = 'Marvel'), 100, 2.99, 'The New 52!', NULL, NULL, 'Court of Owls');

ERROR 1054 (42S22): Unknown column 'COMIC_TITLE_name' in 'field list'

mysql> INSERT INTO COMIC_ISSUE VALUES ('Ironman', 10, '2013-05-15', (SELECT PublisherID from PUBLISHER where name = 'Marvel'), 100, 3.99, 'The secret origin of Tony Stark', NULL, NULL, 'The secret origin of Tony Stark');

ERROR 1054 (42S22): Unknown column 'COMIC_TITLE_name' in 'field list'

mysql> INSERT INTO `cbdb`.`COMIC_ISSUE` VALUES (NULL, 1, '2011-11-01', (SELECT PublisherID from PUBLISHER where name = 'Marvel'), 100, 2.99, 'The New 52!', NULL, NULL, 'Court of Owls');

ERROR 1048 (23000): Column 'COMIC_TITLE_name' cannot be null

最后一个错误很有趣。我尝试插入一个空值（不允许），它抱怨该列不能为null，因此它显然看到了列。请注意，我已经尝试了许多不同的方法，例如“INSERT INTO COMIC_ISSUE”（即没有反引号而没有指定数据库。）我尝试列出所有列。我试着把'蝙蝠侠'放在双引号中，根本没有引号。什么都没做。任何建议都是最受欢迎的。

我认为你的触发器会产生问题。所以试试这个......

CREATE TRIGGER `update_mailbox` AFTER INSERT ON COMIC_ISSUE
FOR EACH ROW 
begin
INSERT INTO MAILBOX_has_COMIC_ISSUE VALUES ((SELECT MAILBOX_mailboxID FROM
MAILBOX_has_COMIC_TITLE WHERE
MAILBOX_has_COMIC_TITLE.COMIC_TITLE_name = new.COMIC_TITLE_name),
(SELECT MAILBOX_CUSTOMER_customerID FROM MAILBOX_has_COMIC_TITLE WHERE
MAILBOX_has_COMIC_TITLE.COMIC_TITLE_name = new.COMIC_TITLE_name), 
new.COMIC_TITLE_name, new.volumeNum,new.coverDate); end$$

在定义触发器时，两个关键字对于SQL语句是唯一的;旧的和新的。

这些关键字允许您在事件触发之前和之后引用数据。

检查一次......
