ReQL command: () (bracket)

Command syntax

sequence(attr) → sequence

singleSelection(attr) → value

object(attr) → value

array(index) → value

Description

Get a single field from an object. If called on a sequence, gets that field from every object in the sequence, skipping objects that lack it.

Example: What was Iron Man’s first appearance in a comic?

r.table('marvel').get('IronMan')('firstAppearance').run(conn, callback)

The () command also accepts integer arguments as array offsets, like the nth command.

Example: Get the fourth element in a sequence. (The first element is position 0, so the fourth element is position 3.)

r.expr([10, 20, 30, 40, 50])(3)

40
