Determine Object_ID of a URL to use with the Facebook Open Graph - facebook

Question

I am trying to learn how to use the Facebook Open Graph API and have a question on how to determine the object_id of my site. I need this object_id so that I can do other queries, such as I want to get a list of users who have liked my site within a given time period.
Based on other Stackoverflow questions I have seen that I should be able to run this query to get the object_id
select id from object_url where url in ('www.bubbasgameroom.com', 'bubbasgameroom.com')
When I run that query it comes back with an empty result. When I run the following query, I see that my page has been liked 21 times
select total_count from link_stat where url in ('www.bubbasgameroom.com', 'bubbasgameroom.com')
What am I missing here? Any help will be greatly appreciated.
Thanks!

Most likely the url should be identical to the og:url meta tag if used on your website. Also you need to append the http:// part for it to work. For example this would work:
SELECT url,site,id
FROM object_url
WHERE url IN (
'http://developers.facebook.com',
'http://www.imdb.com/'
)
Result:
[
{
"url": "http://developers.facebook.com",
"site": "developers.facebook.com",
"id": 113167538713703
},
{
"url": "http://www.imdb.com/",
"site": "www.imdb.com",
"id": 6903354771
}
]
But this doesn't:
SELECT url,site,id
FROM object_url
WHERE url IN (
'developers.facebook.com',
'www.imdb.com/'
)
