Yes - convert the data type to a larger one.
If you've got a mediumint, for example, you can convert it to an
unsigned mediumint. The 'unsigned' bit means that the field won't store
negative values - this gives you twice the positive numbers you can
store. Otherwise if you're already using an unsigned data type, then
just go up to the next data type ( eg mediumint to int, or int to
bigint, etc ).
