Query to check file Version

SELECT

1. fi.file_id,

filename,

version,

1. fi.creation_date file_creation_date,

• ve.creation_date Version_Creation_date

FROM

1. apps.ad_files fi,
2. apps.ad_file_versions ve

WHERE filename LIKE '%pav0212.odf%'

AND ve.file_id = fi.file_id

order by ve.creation_date desc;

Is this a valid query to verify the file versions?. 

When i run this query it shows two versions

Thanks
