ARRAY_SORT

Returns the elements of the input array in ascending order.

If the argument <function> is provided, the sorting order is determined by the result of applying <function> on each element of the array.

Syntax

ARRAY_SORT([<function>,] <array>)

Parameters

Parameter	Description	Supported input type
`<function>`	An optional function to be used to determine the sort order.	Any Lambda function
`<array>`	The array to be sorted.	Any array of integers

Return Type

ARRAY of the same type as the input array

Example

The following examples orders the array levels in ascending order:

SELECT
	ARRAY_SORT([ 4, 1, 3, 2 ]) AS levels;

Returns: 1,2,3,4

In this example below, the modulus operator is used to calculate the remainder on any odd numbers. Therefore ARRAY_ SORT puts the higher (odd) numbers last in the results.

SELECT
	ARRAY_SORT(x -> x % 2, [ 4, 1, 3, 2 ]) AS levels;

Returns: 4,2,1,3
