viirya opened a new issue, #5464:
URL: https://github.com/apache/arrow-datafusion/issues/5464
**Describe the bug**
Comparing decimal dictionary array with scalar value causes an error like:
```
thread
'expressions::binary::tests::comparison_dict_decimal_scalar_expr_test' panicked
at 'called `Result::unwrap()` on an `Err` value: Internal("could not cast value
to
arrow_array::array::primitive_array::PrimitiveArray<arrow_array::types::Decimal128Type>")',
datafusion/physical-expr/src/expressions/binary.rs:1085:17
```
In `compute_decimal_op_dyn_scalar` macro, we shouldn't cast lhs array to
decimal array as it invokes dyn kernel and lhs array could be dictionary array.
