[英]MySQL / phpMyAdmin throws duplicity error on UNIQUE column when no duplicity occurs
I have the following table:我有下表:
CREATE TABLE pret_user (
pret_user_index INT(10) NOT NULL AUTO_INCREMENT PRIMARY KEY,
pret_user_fname VARCHAR(250) NOT NULL,
pret_user_lname VARCHAR(250) NOT NULL,
pret_user_email VARCHAR(250) NOT NULL,
pret_user_telegram_subscribe_token_hash VARCHAR(64) UNIQUE,
pret_user_telegram_subscribe_token_hash_valid_until INT(15),
pret_user_telegram_chat_id INT(15) UNIQUE,
pret_user_telegram_subscribed TINYINT(1) NOT NULL DEFAULT 0
);
when I try to manually update a value of pret_user_telegram_chat_id
, the following error is shown warning of duplicit value in a UNIQUE column even though there is no value with the same value (the table only has 4 rows so I checked manually).当我尝试手动更新
pret_user_telegram_chat_id
的值时,即使没有具有相同值的值(该表只有 4 行,所以我手动检查),也会显示以下错误警告 UNIQUE 列中的重复值。 I've also noticed that while I'm trying to set the value to 5163196961
, the warning is about value 2147483647
.我还注意到,当我尝试将值设置为
5163196961
时,警告是关于值2147483647
的。 Any ideas as to what might be causing this would be much appreciated!任何关于可能导致这种情况的想法将不胜感激!
SQL: SQL:
UPDATE `d28748_admin`.`pret_user`
SET `pret_user_telegram_chat_id` = '5163196931`
WHERE `pret_user`.`pret_user_index` = 2
Error:错误:
#1062 - Duplicate entry '2147483647' for key 'pret_user_telegram_chat_id'
To get around the problem, I switched the column to VARCHAR for the time being and after that the problem disappeared, but I'd really like to get to the bottom of why this happened in case I have a similar problem in the future.为了解决这个问题,我暂时将列切换为 VARCHAR,之后问题就消失了,但我真的很想弄清楚为什么会发生这种情况,以防将来遇到类似的问题。
Your pret_user_telegram_chat_id is too small.您的 pret_user_telegram_chat_id 太小了。 The max value for INT is 2147483647 , even though you've specified 15 spots.
INT 的最大值是 2147483647 ,即使您指定了 15 个点。 You'll want BIGINT instead
你会想要 BIGINT
