nseekhao opened a new issue, #6058:
URL: https://github.com/apache/arrow-datafusion/issues/6058

   ### Describe the bug
   
   The producer failed if the input query `INTERSECT`s `SELECT`s of the same tables and columns multiple time.
   
   ### To Reproduce
   
   ```Rust
       #[tokio::test]
       async fn simple_intersect_table_reuse() -> Result<()> {
           assert_expected_plan(
               "SELECT COUNT(*) FROM (SELECT data.a FROM data INTERSECT SELECT data.a FROM data);",
               "Aggregate: groupBy=[[]], aggr=[[COUNT(UInt8(1))]]\
               \n  LeftSemi Join: data.a = data.a\
               \n    Aggregate: groupBy=[[data.a]], aggr=[[]]\
               \n      TableScan: data projection=[a]\
               \n    TableScan: data projection=[a]",
           )
           .await
       }
   ```
   
   ### Expected behavior
   
   ```bash
   ---- tests::simple_intersect_table_reuse stdout ----
   Error: SchemaError(DuplicateQualifiedField { qualifier: Bare { table: "data" }, name: "a" })
   ```
