> In Hive and Spark engines, the {{AS}} syntax is supported.
> [https://spark.apache.org/docs/latest/sql-ref-syntax-qry-select.html|http://example.com/]
> !image-2025-07-20-03-56-55-568.png!
> However, currently, the Hive and Spark dialects will remove the {{AS}} during
> parsing.
> !image-2025-07-20-04-21-14-158.png|width=709,height=290!
>
> Therefore, we should set the default value of the method:
> {{!image-2025-07-20-03-55-59-759.png|width=655,height=149!}}
> to {{true}} in their respective dialects.
