错误1062(23000):密钥'PRIMARY'的重复条目'2147483647' [英] ERROR 1062 (23000): Duplicate entry '2147483647' for key 'PRIMARY'
问题描述
首先，我已经看到许多其他类似的帖子，但是答案不适用于我的特殊情况. 以防万一我几个月才学习SQL，对此我没有太多的了解.
First off all, i've seen many others post like this, however the answer wasn't working on my particular case. Just in case i am only few months studding SQL, i have no much knowledge on that.
有一张桌子:
CREATE TABLE passenger_details
(
bank_card INT(20) NOT NULL AUTO_INCREMENT,
email VARCHAR(20),
mobile INT(15) NOT NULL,
p_id INT NOT NULL,
PRIMARY KEY (bank_card),
FOREIGN KEY (p_id) REFERENCES passenger(p_id)
);
INSERT INTO passenger_details
VALUES (0123012301230123,'blah_@hotmail.com',0872863492,1234);
select*from passenger_details;
+------------+--------------------+-----------+------+
| bank_card | email | mobile | p_id |
+------------+--------------------+-----------+------+
| 2147483647 | blah_@hotmail.com | 872863492 | 1234 |
+------------+--------------------+-----------+------+
1 row in set (0.00 sec)
我们可以看到，先前的值在表中出错了.应该是16个数字，而不仅仅是10个，实际上是不同的数字.
当我尝试插入新值时:
As we can see, the previous value, just went wrong into table. Should be 16 numbers and not only 10, actually different numbers.
When i try to insert a new value:
INSERT INTO passenger_details
VALUES (1234258431681842,'blah@icloud.com',0895764829,123548);
ERROR 1062 (23000): Duplicate entry '2147483647' for key 'PRIMARY'
如果bank_card是AUTO_INCREMENT，为什么会有错误? 我可以将PK更改到另一个地方吗?
If bank_card is AUTO_INCREMENT why there is error? Shall i change the PK to another place?
真的很感谢您的帮助
推荐答案
INT has a maximum signed value of 2147483647. Any number greater than that will be truncated to that value. What you need to do is change that column to be a varchar(20) which will hold strings of up to 20 characters since bank card numbers are strings and not actually numbers (you don't do math with the). You also should remove AUTO_INCREMENT as that is not a value you will be incrementing.
