> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.0.0

> Priority: Minor
> Fix For: 3.0.0

>
> Previously in from_avro/to_avro, we override the method `simpleString` and
> `sql` for the string output. However, the override only affects the alias
> naming:
> ```
> Project [from_avro('col,
> ...
> , (mode,PERMISSIVE)) AS from_avro(col, struct<col1:bigint,col2:double>,
> Map(mode -> PERMISSIVE))#11]
> ```
> It only makes the alias name quite long.
> We should follow `from_csv`/`from_json` here, to override the method
> prettyName only, and we will get a clean alias name
> ```
> ... AS from_avro(col)#11
> ```
