Note: Support for this method is temporarily disabled until we support user-level permissions. You can still make this call, but you must include your application secret.

Get an object's properties. In order to retrieve data, you need to use data.defineAssociation to define associations for the object.

Parameters

Type	Name	Description
string	api_key	The application key associated with the calling application.
string	session_key	The session key of the logged in user. This parameter is no longer required for this method.
float	call_id	The request's sequence number. Each successive call for any session must use a sequence number greater than the last. We suggest using the current time in milliseconds, such as PHP's microtime(true) function.
string	sig	An MD5 hash of the current request and your secret key, as described in the authentication guide.
string	v	This must be set to 1.0 to use this version of the API.
string	format	Optional - desired response format. Either "XML" (default) or "JSON".
string	callback	Optional - wrap the response inside a function call. This is primarily to enable cross-domain javascript requests using the <script> tag, sometimes known as "JSONP". This works with both XML and JSON.
int64	obj_id	Numeric identifier (fbid) of the object to query.
list	prop_names	Optional - A list of property names (strings) to selectively query a subset of object properties. If not specified, all properties will be returned.

Return Value

An array of the values only (not the names) of specified properties of the object.

Does anyone know what the first property returned (at index 0) represents if you request all the properties? The second (index 1) is the object id (fbid); after that they will be properties you added yourself.

FQL Equivalent

Notes:

• It is required to prefix object type's name "my_table" with "app." to avoid name collisions with Facebook tables.
• In FQL, object id is a built-in field with a name of "_id".

SELECT prop1, prop2 FROM app.my_table WHERE _id = 12345;
