Command syntax

Description

Compute the logical “and” of one or more values.

The and command can be used as an infix operator after its first argument (r.expr(true).and(false)) or given all of its arguments as parameters (r.and(true, false)). The standard Ruby or operator, |, may also be used with ReQL.

Calling and with zero arguments will return true.

Example: Return whether both a and b evaluate to true.

> a = true
> b = false
> (r.expr(a) & b).run(conn)

false

Example: Return whether all of x, y and z evaluate to true.

> x = true
> y = true
> z = true
> r.and(x, y, z).run(conn)

true
