Or

Or(value_1, value_2, ...)

Description

The Or function operates on one or more values and returns true if at least one of the values is "true", and false otherwise.

Prior to version 3.0.0, all items in the value list were evaluated. With version 3.0.0, evaluation is short-circuited when a true value is encountered. For example, a collection is no longer created with this query:

Or(true, CreateCollection({ name: "test" }))
Or does not support parameters that include Objects, Arrays, Pages, Sets, or FQL expressions. The similar Any function supports Arrays, Pages, and type:[]sets.

Parameters

Parameter Type Definition and Requirements

value

Boolean

One or more Boolean values.

Returns

A Boolean value.

Examples

The following query returns true because at least one of the provided values is "true":

try
{
    Value result = await client.Query(
        Or(true, true, false)
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
BooleanV(True)
result, err := client.Query(
	f.Or(true, true, false))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
true
System.out.println(
    client.query(
        Or(Value(true), Value(true), Value(false))
    ).get());
true
client.query(
  q.Or(true, true, false)
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
true
result = client.query(
  q.or_(True, True, False)
)
print(result)
True
Or(true, true, false)
true
