[jira] [Updated] (SPARK-27906) Improve parser error message for
CREATE LOCAL TEMPORARY TABLE statement
[ https://issues.apache.org/jira/browse/SPARK-27906?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dongjoon Hyun updated SPARK-27906:
----------------------------------
Affects Version/s: (was: 3.0.0)
3.1.0
> Improve parser error message for CREATE LOCAL TEMPORARY TABLE statement
> -----------------------------------------------------------------------
>
> Key: SPARK-27906
> URL: https://issues.apache.org/jira/browse/SPARK-27906
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Yesheng Ma
> Priority: Major
>
> The {{CREATE LOCAL TEMPORARY TABLE}} statement is actually not supported in Spark SQL. However, when a user queries such a statement, the error message is confusing. For example, the error message for
> {code:sql}
> CREATE LOCAL TEMPORARY TABLE my_table (x INT);
> {code}
> is
> {code:java}
> no viable alternative at input 'CREATE LOCAL'(line 1, pos 7)
> {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}
> CREATE LOCAL TEMPORARY TABLE statements are not supported.
> {code}
