             Summary: A temporary table associated with a WITH clause should (probably) not be treated as a table by TableVisitor
                 Key: IMPALA-13767
                 URL: https://issues.apache.org/jira/browse/IMPALA-13767
             Project: IMPALA
          Issue Type: Bug
          Components: Frontend
            Reporter: Fang-Yu Rao
            Assignee: Fang-Yu Rao


Currently a temporary table associated with a WITH clause is treated as a table by {{TableVisitor}} in [CalciteMetadataHandler.java|https://github.com/apache/impala/blob/master/java/calcite-planner/src/main/java/org/apache/impala/calcite/service/CalciteMetadataHandler.java].

 

For instance, after the execution of "{{{}parsedNode.accept(tableVisitor){}}}" in CalciteMetadataHandler.java, '{{{}tableVisitor.tableNames_{}}}' evaluates to a {{HashSet}} consisting of the table names "{{{}default.t{}}}" and "{{{}functional.alltypestiny{}}}" for the following query. It would be better if "{{{}default.t{}}}" is not considered as a name of a table involved in the query when we are visiting the {{SqlNode}}.
{code:java}
with t as (select * from functional.alltypestiny) select * from t;
{code}
