As you suggested I went on the DB route. These are my findings for future
reference:
 I ran the same (or equivalent where applicable) query in:
MySql 5.6: Success
MySql 5.7.23: Failure
MySql 8.0.12: Success
Postgres server 10.5: Success
MSSQL 2016: Success

I attach the query for the curious.

Thanks.
