alamb opened a new issue, #3733:
URL: https://github.com/apache/arrow-datafusion/issues/3733
**Describe the bug**
A clear and concise description of what the bug is.
**To Reproduce**
Put in `core/src/dataframe.rs`
```rust
#[tokio::test]
async fn select_with_periods() -> Result<()> {
// define data with a column name that has a "." in it:
let array: Int32Array = [1, 10].into_iter().collect();
let batch =
RecordBatch::try_from_iter(vec![("f.c1", Arc::new(array) as
_)]).unwrap();
let ctx = SessionContext::new();
ctx.register_batch("t", batch).unwrap();
let df = ctx
.table("t")
.unwrap()
.select_columns(&["f.c1"])
.unwrap();
let df_results = df.collect().await.unwrap();
assert_batches_sorted_eq!(
vec![
"+------+",
"| f.c1 |",
"+------+",
"| 1 |",
"| 10 |",
"+------+",
],
&df_results
);
Ok(())
}
```
Fails like:
```
thread 'dataframe::tests::select_with_periods' panicked at 'called
`Result::unwrap()` on an `Err` value: SchemaError(FieldNotFound { qualifier:
Some("f"), name: "c1", valid_fields: Some(["t.f.c1"]) })',
datafusion/core/src/dataframe.rs:1437:14
```
**Expected behavior**
The test should pass
**Additional context**
