mysql - MySQL は別の番号を更新します

Question

update profiles_profiles set unconfirmed_phone=2222222222 where id = 1;


mysql> select * from profiles_profiles\G
*************************** 1. row ***************************
               id: 1
          user_id: 1
            phone: NULL
unconfirmed_phone: 2147483647

何らかの理由で、「2222222222」で更新が機能しません。ただし、1111111111 で動作します。

MySQL は常に他のすべてのフィールドを更新しますが、毎回 unconfirmed_phone を 2147483647 に変更します。

mysql> desc profiles_profiles;
