Yonik Seeley commented on SOLR-7643:
------------------------------------

I haven't tried it in this specific scenario, but there is also a field() function to reference a problematic field name:
example:  exists(field('#table_name'))

> I have some index documents with both table_name and #table_name fields.
> If I use a function query with table_name:
> SolrQuery query = new SolrQuery();
> query.add("fl" , "exists(table_name)");
> it works, returning results like this: <doc><bool name="exists(table_name)">true</bool></doc> 
> However, if I use #table_name:
>  
> query.add("fl" , "exists(#table_name)");
> it returns empty documents like this: <doc></doc>
