Weijun-H opened a new issue, #9706:
URL: https://github.com/apache/arrow-datafusion/issues/9706
### Describe the bug
It seems that the functions `array_union` and `array_intersect` are unable
to process columnar data that contains NULL values. These NULL values are being
overlooked in the process.
### To Reproduce
``` bash
❯
CREATE TABLE array_intersect_table
AS VALUES
([1, 2, 2, 3], [2, 3, 4]),
([2, 3, 3], [3]),
([3], [3, 3, 4]),
(null, [3, 4]),
([1, 2], null),
(null, null)
;
0 rows in set. Query took 0.013 seconds.
❯ select array_intersect(column1, column2) from array_intersect_table;
+------------------------------------------------------------------------+
| array_intersect(array_intersect_table.column1,array_except_table.column2) |
+------------------------------------------------------------------------+
| [2, 3] |
| [3] |
| [3] |
+------------------------------------------------------------------------+
3 rows in set. Query took 0.007 seconds.
```
