Why can't I insert 10 digits when my column is INT(10)

Question

I have this column that\'s INT(10) ZEROFILL NOT NULL DEFAULT \'0000000000\',

But when I insert something like 9100000010, I get 42949

Answer 1

Int has maximum value range :

INT 4   -2147483648 2147483647
        0   4294967295 (unsigned )

hence, you are getting the maximum value due to the overflow. use bigint instead, which has 8 bytes and you shall be fine.

BIGINT  8   -9223372036854775808    9223372036854775807
          0                 18446744073709551615
