Dongjoon Hyun updated SPARK-27904:
----------------------------------
Affects Version/s: (was: 3.0.0)
3.1.0
> Improve parser error message for SHOW VIEW statement
> ----------------------------------------------------
>
> Key: SPARK-27904
> URL: https://issues.apache.org/jira/browse/SPARK-27904
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Yesheng Ma
> Priority: Major
>
> {{SHOW VIEW}} statement is actually not supported in Spark SQL. However, when
> a user quries such a statement, the error message is confusing. For example,
> the error message for
> {code:sql}
> SHOW VIEWS IN my_database
> {code}
> is
> {code:java}
> missing 'FUNCTIONS' at 'IN'(line 1, pos 11)
> {code}
> which is misleading.
>
> One possible way to fix is to explicitly capture these statements in a
> grammar rule and print user-friendly error message such as
> {code:java}
> SHOW VIEW statements are not supported.
> {code}
