### What changes were proposed in this pull request? This PR addresses two things: - `SHOW TBLPROPERTIES` should supports view (a regression introduced by #26921) - `SHOW TBLPROPERTIES` on a temporary view should return empty result (2.4 behavior instead of throwing `AnalysisException`. ### Why are the changes needed? It's a bug. ### Does this PR introduce any user-facing change? Yes, now `SHOW TBLPROPERTIES` works on views: ``` scala> sql("CREATE VIEW view TBLPROPERTIES('p1'='v1', 'p2'='v2') AS SELECT 1 AS c1") scala> sql("SHOW TBLPROPERTIES view").show(truncate=false) +---------------------------------+-------------+ |key |value | +---------------------------------+-------------+ |view.catalogAndNamespace.numParts|2 | |view.query.out.col.0 |c1 | |view.query.out.numCols |1 | |p2 |v2 | |view.catalogAndNamespace.part.0 |spark_catalog| |p1 |v1 | |view.catalogAndNamespace.part.1 |default | +---------------------------------+-------------+ ``` And for a temporary view: ``` scala> sql("CREATE TEMPORARY VIEW tview TBLPROPERTIES('p1'='v1', 'p2'='v2') AS SELECT 1 AS c1") scala> sql("SHOW TBLPROPERTIES tview").show(truncate=false) +---+-----+ |key|value| +---+-----+ +---+-----+ ``` ### How was this patch tested? Added tests. Closes #28375 from imback82/show_tblproperties_followup. Authored-by: Terry Kim <yuminkim@gmail.com> Signed-off-by: Wenchen Fan <wenchen@databricks.com> |
