Block Queries

Before you begin this section, you should have completed the Intermediate Querying Lesson or have a good understanding of basic Fluree queries. Completion of the Flakes and Blocks Lesson or a good understanding of flakes is also helpful. In addition, you should know about the subject-predicate-object model.

Querying Blocks​

If we want to see all of the flakes that belong to a particular block, you can use a block number, an ISO-8601 formatted string or an ISO-8601 formatted duration.

Using block number:

{
  "block": 4
}

Using ISO-8601 formatted wall clock time:

{
  "block": "2017-11-14T20:59:36.097Z"
}

Using ISO-8601 formatted duration (as of 1 hour ago):

{
  "block": "PT1H"
}

Use this resource on the [ISO-8601 duration format](https://www.digi.com/resources/documentation/digidocs/90001437-13/reference/r_iso_8601_duration_format.htm) to see all the flakes from 3 months, 2 days, 6 hours, and 2 minutes ago.
