---------------------------------
Summary: UnresolvedV2Relation should be resolved to temp view first
Key: SPARK-30282
URL: https://issues.apache.org/jira/browse/SPARK-30282
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 3.0.0
Reporter: Terry Kim
For the following v2 commands, _Analyzer.ResolveTables_ does not check against
the temp views before resolving _UnresolvedV2Relation_, thus it always resolves
_UnresolvedV2Relation_ to a table:
* ALTER TABLE
* DESCRIBE TABLE
* SHOW TBLPROPERTIES
Thus, in the following example, 't' will be resolved to a table, not a temp
view:
{code:java}
sql("CREATE TEMPORARY VIEW t AS SELECT 2 AS i")
sql("CREATE TABLE testcat.ns.t USING csv AS SELECT 1 AS i")
sql("USE testcat.ns")
sql("SHOW TBLPROPERTIES t") // 't' is resolved to a table
{code}
For V2 commands, if a table is resolved to a temp view, it should error out
with a message that v2 command cannot handle temp views.
