Differences between int (2) and int (10) in MySQL

N in Int (n) is not a restricted field, the range of values for int is fixed (0 to 4294967295) or (-2147483648 to 2147483647)

Then n this value is for zero when the value in the field is insufficient, but must contain zerofill, for example

CREATE table ' type ' (' ID ' int (8) Zerofill unsigned not null,primary key (' id ')) engine=innodb default Charset=utf8;

If you insert 8888, the data you view should be 00008888, and if you insert 1111111111111, the data you view should be 4294967295

If int does not specify N, the default is the 10,unsigned property determines whether the value is signed, and if so, the value range is (0 to 4294967295)
