simicd opened a new issue, #259:
URL: https://github.com/apache/arrow-datafusion-python/issues/259
**Is your feature request related to a problem or challenge? Please describe
what you are trying to do.**
The functions introduced with #241 currently do not allow to specify a table
name. By default the table name is a random hash making SQL queries more
difficult to use.
**Describe the solution you'd like**
Be able to set table name in the `from_...` functions.
**Before:**
```python
ctx.from_pydict({"a": [1, 2, 3], "b": [4, None, 6]}) # -> Would
like to set table name here...
table_name = ctx.catalog().database().names().pop() # ❌ ... so that table
name is known and doesn't have to be derived like this
result_df = ctx.sql(f"select a, is_null(b) as b_is_null from {table_name}")
```
**After:**
```python
ctx.from_pydict({"a": [1, 2, 3], "b": [4, None, 6]}, name="t")
result_df = ctx.sql(f"select a, is_null(b) as b_is_null from t")
```
Additionally update the UDF/UDAF SQL example introduced in PR #258
