Model find issue with string input for number

[mybigman]

Appears to be a bug but not sure hence posting here first.

primary key is order_id

Order.find(25) // returns object details as expected (if exists)

Order.find(999999) // returns null as expected (if not exists)

Order.find('a25') // returns object details of order number 0 NOT expected, expecting null

Its appears its taking the string value and forcing it to be a 0.

What is the type of order_id column in migration table and model?
