Facebook Query Language (FQL) is a query language that allows querying Facebook user data by using a SQL-style interface,[1] avoiding the need to use the Facebook Platform Graph API.[2] Data returned from an FQL query is in JSON format by default.
FQL was first made publicly available in February 2007.[3]
FQL will no longer be available as of August 7, 2016, when Facebook API 2.0 is no longer available.[4] Facebook API versions newer than API 2.0 do not support FQL.
