Question

这是我的桌子

mysql> describe clients;
+------------+---------------------------------+------+-----+---------+----------------+
| Field      | Type                            | Null | Key | Default | Extra          |
+------------+---------------------------------+------+-----+---------+----------------+
| id         | int(11)                         | NO   | PRI | NULL    | auto_increment |
| name       | varchar(50)                     | YES  |     | NULL    |                |
| membership | enum('Silver','Gold','Diamond') | YES  |     | NULL    |                |
| interest   | set('Movie','Music','Concert')  | YES  |     | NULL    |                |
+------------+---------------------------------+------+-----+---------+----------------+
4 rows in set (0.00 sec)

如果我尝试

INSERT INTO clients (name, membership,interest) VALUES ('Pizda','Gold', 'Music'),('Kratez','Premium', 'Movie,Concert');

比我有问题

ERROR 1265 (01000): Data truncated for column 'membership' at row 2

截断的数据指的是什么？

Answer 1

枚举membership | enum('Silver','Gold','Diamond')没有值Premium。

CREATE TABLE clients(
  id INT(11) PRIMARY KEY AUTO_INCREMENT,
   membership  enum('Silver','Gold','Diamond') 
);

INSERT INTO clients(membership)
VALUES('Premium');
-- Data truncated for column 'membership' at row 1

INSERT INTO clients(membership)
VALUES(NULL);

错误1265（01000）：第2行的列'membership'的数据被截断
