What is the correct Doctrin's column type for MySql's YEAR type

Question

I want to map a property from one of my doctrine's entity to a table's column with datatype of YEAR.

At the moment I'm using the doctrine's integer type with the length of 4 as demonstrated bellow, but I was wondering if there is a better match for such mapping.

/**
 * @var integer
 *
 * @ORM\Column(name="year", type="integer", length=4, nullable=true)
 */
private $year;

Answer 1

Any exact numeric type should be ok
