Answer 1

您不能将文本存储在数字数据类型的列中。您必须将数据类型更改为char(14).

ALTER TABLE your_table MODIFY myfield CHAR(14);

Answer 2

如果您运行该特定查询，并且仅4563插入，则建议您将“myfield”的列类型设置为“int”的某个变体或长度而不是 char(22)（CCN 并不总是 16 位，有些可以为 20 或 22）。

您可能应该切换列类型以确保数据正确插入到类似

ALTER TABLE mytable MODIFY myfield char(22);

Answer 3

insert into mytable ('myfield') values ('4563******3245');

它工作正常

确保您的列类型应该是 varchar
