andygrove opened a new issue, #2372:
URL: https://github.com/apache/arrow-datafusion/issues/2372

   **Describe the bug**
   See the test case below
   
   **To Reproduce**
   ``` rust
   #[tokio::test]
   async fn query_cte_with_alias() -> Result<()> {
       let ctx = SessionContext::new();
       let schema = Schema::new(vec![
           Field::new("id", DataType::Int16, false),
           Field::new("a", DataType::Int16, false),
       ]);
       let empty_table = Arc::new(EmptyTable::new(Arc::new(schema)));
       ctx.register_table("t1", empty_table)?;
       let sql = "with \
           v1 as (select * from t1), \
           v2 as (select * from v1, v1 v1a, v1 v1b where v1a.id = v1.id - 1 and v1b.id = v1.id + 1) \
           select * from v2";
       let actual = execute_to_batches(&ctx, sql).await;
       let expected = vec![
           "+----------+",
           "| Int64(1) |",
           "+----------+",
           "| 1        |",
           "+----------+",
       ];
       assert_batches_eq!(expected, &actual);
       Ok(())
   }
   ```
   
   Fails with:
   
   ```
   Schema contains duplicate qualified field name 'v1.id'
   ```
   
   **Expected behavior**
   Should not fail
   
   **Additional context**
   None
