llama90 opened a new issue, #39050:
URL: https://github.com/apache/arrow/issues/39050
### Describe the enhancement requested
This is a sub-issue of the issue mentioned below.
* #35560
As we can see in the parent issue, we can find tables organizing the related
functions.
| file name | code snippet
|
|-------------------|--------------------------------------------------------------------------------------------|
| scalar_test.cc | `TimestampScalar(value,
timestamp(in)).CastTo(timestamp(out)).ValueOrDie();` | 2 |
| scalar_test.cc | `TimestampScalar(1024,
timestamp(TimeUnit::MILLI)).CastTo(utf8()));` |
| scalar_test.cc | `TimestampScalar(1024,
timestamp(TimeUnit::MILLI)).CastTo(int64()));` |
| scalar_test.cc | `.CastTo(date64()));`
|
> The functions require handling "ValueOrDie called on an error: Invalid:
Casting from timestamp[ns] to timestamp[us] would lose data: 1234" error.
We need to implement casting between different `Timestamp` types.
