URL: https://github.com/apache/datafusion/issues/18101#issuecomment-3414231498
Could you provide a reproduction? I tried following the steps you described
but I can't reproduce the issue.
CSV file:
```csv
name_1,num,"Column Name"
andrew,100,1
jorge,200,2
andy,150,3
paul,300,4
```
Test case, running on latest main:
```rust
use datafusion::dataframe::DataFrameWriteOptions;
use datafusion::error::Result;
use datafusion::prelude::*;
#[tokio::main]
async fn main() -> Result<()> {
let ctx = SessionContext::new();
let df = ctx
.read_csv(
"/Users/jeffrey/Downloads/test.csv",
CsvReadOptions::default(),
)
.await?;
df.clone().show().await?;
df.select(vec![col("Column Name").alias("column_name"), col("num")])?
.write_parquet("test.parquet", DataFrameWriteOptions::default(),
None)
.await?;
ctx.read_parquet("test.parquet", ParquetReadOptions::default())
.await?
.show()
.await?;
Ok(())
}
```
Output:
```sh
datafusion (main)$ cargo run --example dataframe
