What is the columnDefinition in an XSD for a bigInt(21) field.

I created a view in SQL to calculate the age of a person.  MariaDB is formating the age field as a bigint(21).  I am connecting an CDT to this view and I need to know what the columnDefinition would be for a big integer.  I tried INT and BIGINT and that doesn't work.

        
          @Column(name="Age", columnDefinition="INT")
        
      

I even tried to cast the calculated field as an integer in the SQL statement, but that did not work either?

CAST(TIMESTAMPDIFF(YEAR, `CM`.`ClergyDOB`,
              CASE
              WHEN `CM`.`ClergyDOD` IS NULL THEN CURDATE()
              ELSE `CM`.`ClergyDOD`
END
)
AS INT) AS `Age`,
