duration::max

The duration::max constant represents the greatest possible duration that can be used.

duration::max -> duration

Some examples of the constant in use:

duration::max;

duration::max + 1ns;

100y IN 0ns..duration::max

-------- Query 1 --------

584942417355y3w5d7h15s999ms999µs999ns

-------- Query 2 --------
'Failed to compute: "584942417355y3w5d7h15s999ms999µs999ns + 1ns", as the operation results in an arithmetic overflow.'

-------- Query 3 --------
true

duration::years

The duration::years function counts how many years fit into a duration.

duration::years(duration) -> number

The following example shows this function, and its output, when used in a RETURN statement:

RETURN duration::years(300w);

-- 5

duration::from_days

The duration::from_days function counts how many years fit into a duration.

duration::from_days(number) -> duration

The following example shows this function, and its output, when used in a RETURN statement:

RETURN duration::from_days(3);

-- 3d

duration::from_hours

The duration::from_hours function converts a numeric amount of hours into a duration that represents hours.

duration::from_hours(number) -> duration

The following example shows this function, and its output, when used in a RETURN statement:

RETURN duration::from_hours(3);

-- 3h

duration::from_micros

The duration::from_micros function converts a numeric amount of microseconds into a duration that represents microseconds.

duration::from_micros(number) -> duration

The following example shows this function, and its output, when used in a RETURN statement:

RETURN duration::from_micros(3);

-- 3μs

duration::from_millis

The duration::from_millis function converts a numeric amount of milliseconds into a duration that represents milliseconds.

duration::from_millis(number) -> duration

The following example shows this function, and its output, when used in a RETURN statement:

RETURN duration::from_millis(3);

-- 3ms

duration::from_mins

The duration::from_mins function converts a numeric amount of minutes into a duration that represents minutes.

The following example shows this function, and its output, when used in a RETURN statement:

RETURN duration::from_mins(3);

-- 3m

duration::from_nanos

The duration::from_nanos function converts a numeric amount of nanoseconds into a duration that represents nanoseconds.

duration::from_nanos(number) -> duration

The following example shows this function, and its output, when used in a RETURN statement:

RETURN duration::from_nanos(3);

-- 3ns

duration::from_secs

The duration::from_secs function converts a numeric amount of seconds into a duration that represents seconds.

RETURN duration::from_secs(3);

-- 3s

duration::from_weeks

The duration::from_weeks function converts a numeric amount of weeks into a duration that represents weeks.

duration::from_weeks(number) -> duration

The following example shows this function, and its output, when used in a RETURN statement:

RETURN duration::from_weeks(3);

-- 3w

Method chaining

Method chaining allows functions to be called using the . dot operator on a value of a certain type instead of the full path of the function followed by the value.

-- Traditional syntax
duration::mins(2d6h);

-- Method chaining syntax
2d6h.mins();

3240

This is particularly useful for readability when a function is called multiple times.

-- Traditional syntax
duration::mins(duration::from_millis(98734234));

-- Method chaining syntax
duration::from_millis(98734234).mins();
