| // inside a view maybe resolved incorrectly. | ||
| // But for commands like `DropViewCommand`, resolving view is unnecessary even though | ||
| // there is unresolved node. So use the `performCheck` flag to skip the analysis check | ||
| // for these commands. |

This trick doesn't always work. Sometimes the analyzer may fail eagerly instead of waiting for checkAnalysis.

Hm, the scala-2.13 build failure seems to be not related to this PR and it is reported in https://issues.apache.org/jira/browse/SPARK-34762. |

…DDL commands For DDL commands like DROP VIEW, they don't really need to resolve the view (parse and analyze the view SQL text), they just need to get the view metadata. This PR fixes the rule `ResolveTempViews` to only resolve the temp view for `UnresolvedRelation`. This also fixes a bug for DROP VIEW, as previously it tried to resolve the view and failed to drop invalid views. bug fix no new test Closes #31853 from cloud-fan/view-resolve.
