Mellorsssss opened a new issue, #18064: URL: https://github.com/apache/doris/issues/18064
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Description As the support for structs in Doris is not complete, some functions have been added to compensate. Furthermore, the output scale of DateTimeV2 within the struct is incorrect and requires correction. For example: ``` mysql> select array_zip(array(cast ('2023-03-05 12:23:24.999' as datetimev2(1)),cast ('2023-03-05 15:23:23.997' as datetimev2(3)))); +----------------------------------------------------------------------------------------------------------------------+ | array_zip(array(CAST('2023-03-05 12:23:24.999' AS DATETIMEV2(1)), CAST('2023-03-05 15:23:23.997' AS DATETIMEV2(3)))) | +----------------------------------------------------------------------------------------------------------------------+ | [{2023-03-05 12:23:24.999000}, {2023-03-05 15:23:23.997000}] | +----------------------------------------------------------------------------------------------------------------------+ 1 row in set (0.01 sec) ``` The expected output should be: ``` mysql> select array_zip(array(cast ('2023-03-05 12:23:24.999' as datetimev2(1)),cast ('2023-03-05 15:23:23.997' as datetimev2(3)))); +----------------------------------------------------------------------------------------------------------------------+ | array_zip(array(CAST('2023-03-05 12:23:24.999' AS DATETIMEV2(1)), CAST('2023-03-05 15:23:23.997' AS DATETIMEV2(3)))) | +----------------------------------------------------------------------------------------------------------------------+ | [{2023-03-05 12:23:24.999}, {2023-03-05 15:23:23.997}] | +----------------------------------------------------------------------------------------------------------------------+ 1 row in set (0.01 sec) ``` ### Solution Currently, Doris uses the scale of an array's child element to represent the scale of a nested type. However, for structs, we may need to use the scale of the individual field to represent the scale of the entire struct. ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
