delamarch3 opened a new issue, #7182:
URL: https://github.com/apache/arrow-rs/issues/7182
**Describe the bug**
<!--
A clear and concise description of what the bug is.
-->
It looks like `date_part` using an interval will return the whole interval
instead of taking out the part.
**To Reproduce**
<!--
Steps to reproduce the behavior:
-->
```rust
use arrow::array::{Int32Array, IntervalMonthDayNanoArray,
TimestampSecondArray};
use arrow::compute::{date_part, DatePart};
use arrow::datatypes::IntervalMonthDayNano;
fn main() -> Result<(), Box<dyn std::error::Error>> {
let array = TimestampSecondArray::from(vec![305]); // 5 minutes, 5
seconds
let result = date_part(&array, DatePart::Second)?
.as_any()
.downcast_ref::<Int32Array>()
.unwrap()
.iter()
.collect::<Vec<Option<i32>>>();
assert_eq!(result, &[Some(5)]); // As expected
let array = IntervalMonthDayNanoArray::from(vec![
IntervalMonthDayNano::new(0, 0, 305 * 1_000_000_000), // 0 months, 0
days, 305 seconds
]);
let res: Vec<Option<i32>> = date_part(&array, DatePart::Second)?
.as_any()
.downcast_ref::<Int32Array>()
.unwrap()
.iter()
.collect::<Vec<Option<i32>>>();
assert_eq!(res, &[Some(5)]); // Fails, result is 305
Ok(())
}
```
**Expected behavior**
<!--
A clear and concise description of what you expected to happen.
-->
`date_part` returns the requested part.
