[GitHub] [arrow-datafusion] viirya opened a new issue, #5150: Arithmetic scalar operation doesn't work with DictionaryArray

viirya opened a new issue, #5150:
URL: https://github.com/apache/arrow-datafusion/issues/5150

   **Describe the bug**
   
   We've integrated Datafusion but recently saw an exception during evaluating arithmetic operation between DictionaryArray and scalar value:
   
   ```
   'Dictionary(Int32, Int64) + Int64' can't be evaluated because there isn't a common type to coerce the types to.  
   ```
   
   A few issues around this:
   
   * `binary_operator_data_type` calls `coerce_types` to coerce left and right data types, but it doesn't consider `Dictionary` type. in `mathematics_numerical_coercion`.
   * In `BinaryExpr.evaluate_array_scalar`, the macros for arithmetic operations (`Plus` etc.) also don't consider `DictionaryArray`.
