> ArrayRemove() Function Need Remove NULL Value
> ---------------------------------------------
>
> Key: SPARK-49520
> URL: https://issues.apache.org/jira/browse/SPARK-49520
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.2.1
> Environment: *Spark Version: 3.2.1*
> Reporter: Feng Jie
> Priority: Major
> Labels: Function, SQL
> Attachments: image-2024-09-06-09-52-45-339.png

> Original Estimate: 168h
> Remaining Estimate: 168h

> I want to calculate the intersection of two arrays like this:
> {noformat}
> select
> case when intersect_size > 0 then 1 else 0 end as is_include
> from (
> select
> size(array_intersect(array_a, array_b)) as intersect_size
> from table_a
> )
> {noformat}
>
> But, the NULL will affect the output:
> {code:java}
> SELECT size(array_intersect(array(1, 2, 3, null), array(null)))
> Output: 1 {code}
> So I want remove the NULL in first array by using {*}array_remove{*}：
> {code:java}
> SELECT array_remove(array(1, 2, 3, null, 3), null)
> Output: null{code}
> I want to add extra logic for function *array_remove* to remove NULL. Shall I
> overwrite the function (May be named: array_remove(array_a, array_b,
> isIgnoreNull)) or just fix the original function?
