If you have a date column with null filters you are not able to use field filters. This is happening with the latest driver 1.5.0
Just create a table with one column of type date or datetime and add data including some null values.
Then just try to apply a field filter and it breaks
I want to be able to use field filters on date columns that havenull values
null
Code: 349. DB::Exception: Cannot convert NULL value to non-Nullable type: while executing 'FUNCTION CAST(updated_at : 0, 'date' :: 1) -> CAST(updated_at, 'date') Date : 4': While executing MergeTreeSelect(pool: PrefetchedReadPool, algorithm: Thread).
