Using Month and year only to get all data

[hsteo]

I would like to find out if extraction of data from database is possible by using the mm/yyyy only.

My code is as below but it is not a workable code:

SELECT vessel, voyage
FROM dneirout 
WHERE CONVERT(DATETIME, dneirout.CONTAINER_OUT_DATE, 103) >=  CONVERT(DATETIME, '09/2008', 103)
