Thank you for the investigation @rkrishn7 🙏
> Hello! I've dug into this issue a bit and it seems that the problem here
arises from the fact that the table name for each table scan in the plan
defaults to UNNAMED_TABLE ("?table?").
When I tested this reproducer last, when I disabled
`datafusion.execution.parquet.schema_force_view_types` (set it to false) then
the query would run
This suggests to me the problem wasn't related to ambiguous schemas but
instead somehow to some type coercion that was/wasn't happening 🤔
I would have thought this code was coerceing the join predicates already:
https://github.com/apache/datafusion/blob/d42b99474691a263c1dd53179e9ad1b481b1e819/datafusion/optimizer/src/analyzer/type_coercion.rs#L193-L192
But clearly something isn't working
