FQL v4 will be decommissioned on June 30, 2025. Ensure that you complete your migration from FQL v4 to FQL v10 by that date.

For more details, review the migration guide. Contact support@fauna.com with any questions.

LT

This reference topic applies to FQL v4. Go to this page for the latest FQL v10 reference topics.

 
LT(value_1, value_2, ...)
lt(value_1, value_2, ...)
LT(value_1, value_2, ...)
LT(value_1, value_2, ...)
LT(value_1, value_2, ...)

Description

The LT function returns true if each specified value is less than the ones following it, and false otherwise. The function takes one or more arguments; it always returns true if it has a single argument.

Types have an order of precedence. When comparing values of different types, they are ranked in the following order, from least to greatest.

  1. Number (integers and decimals: 0.5 < 1 < 1.5 < 2)

  2. Byte

  3. String

  4. Array (ordered lexically, like strings)

  5. Object (ordered lexically, like strings)

  6. Reference

  7. Timestamp

  8. Date

  9. Boolean (false < true)

  10. Null

This means that any Number is always less than any Array.

Parameters

Parameter Type Definition and Requirements

value

Any

A value to be compared.

Returns

A Boolean value indicating whether each value is less than the subsequent values.

Examples

The following query returns true because the value 1 is less than the value 2, and the value 2 is less than the value 3:

client.query(
  q.LT(1, 2, 3)
)
.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.lt(1, 2, 3)
)
print(result)
True
result, err := client.Query(
	f.LT(1, 2, 3))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
true
try
{
    Value result = await client.Query(
        LT(1, 2, 3)
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
BooleanV(True)
LT(1, 2, 3)
