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" })
```
