> -------------------------------------------------------------

> Key: SPARK-22488
> URL: https://issues.apache.org/jira/browse/SPARK-22488
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.1.2, 2.2.0
> Reporter: Xiao Li
> Assignee: Xiao Li
>
> The current internal `table()` API of `SparkSession` bypasses the Analyzer and directly calls `sessionState.catalog.lookupRelation` API. This skips the view resolution logics in our Analyzer rule `ResolveRelations`. This internal API is widely used by various DDL commands or the other internal APIs.
> Users might get the strange error caused by view resolution when the default database is different.
