> Unable to Alter the Temporary View Using ALTER VIEW command
> -----------------------------------------------------------
>
> Key: SPARK-17180
> URL: https://issues.apache.org/jira/browse/SPARK-17180
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Xiao Li
> Fix For: 2.1.0
>
>
> In the current master branch, when users do not specify the database name in
> the `ALTER VIEW AS SELECT` command, we always try to alter the permanent view
> even if the temporary view exists.
> The expected behavior of `ALTER VIEW AS SELECT` should be like: alters the
> temporary view if the temp view exists; otherwise, try to alter the permanent
> view. This order is consistent with another command `DROP VIEW`, since users
> are unable to specify the keyword TEMPORARY.
