Comments

Create, update, delete, and query the Comments for a Target. Comments may also be inserted based on a Target or deleted based on Id.

Table Specific Information

Comments in Facebook are comments about a specific thing. They are always associated with a target, which is the item the comment is directed toward. For example, this could be a post, a picture, or a video. Using this table, you can list the comments for a specific target and also insert new comments about a target.

Select

When querying comments, either the Target or the Id of the comment must be specified. For example, to retrieve all the comments about a specific post, your SELECT statement could look something like this:

SELECT * FROM Comments WHERE Target = '15526475270_410830705612736'

Alternatively, you can specify the Id to retrieve a specific comment. For example:

SELECT * FROM Comments WHERE Id = '15526475270_410830705612736_5193593'

Insert

To insert a comment, you will need to specify a Target and a Message. The target represents the Id of a post, picture, video, or another valid Id for making comments to. For example:

INSERT INTO Comments (Target, Message) VALUES ('PostId', 'This is a sample message.')

Update

Facebook does not allow comments to be modified.

Delete

Comments may be deleted by providing the Id of the comment and issuing a DELETE statement. Please note that Facebook allows only comments created by your app to be deleted using your app.
