update profiles_profiles set unconfirmed_phone=2222222222 where id = 1;
mysql> select * from profiles_profiles\G
*************************** 1. row ***************************

unconfirmed_phone: 2147483647
出于某种原因，我的更新不适用于“2222222222”。但是，它适用于 1111111111。
MySQL 始终会更新所有其他字段，但每次都会将 unconfirmed_phone 更改为 2147483647。
mysql> desc profiles_profiles;

最佳答案
它只是意味着你要更新当前值的新值只是溢出了。 signed int 的最大允许值为 2147483647。
有时电话号码的数据类型可以简单地为 varchar，因为其他人用 (, ), - 等符号保存它
手册摘录，
The maximum value depends on the system. 32 bit systems have a maximum signed integer range of -2147483648 to 2147483647. So for example on such a system, intval('1000000000000') will return 2147483647. The maximum signed integer value for 64 bit systems is 9223372036854775807.
