Hi Andrea,
Thanks for your reply. Your proposal sounds good to me. I'll open a Jira item
and prepare a pull request.
Cheers,

HI Stefan,
a virtual table can be built around any resultset returning statement
(e.g., a stored procedure), and the JDBCDataStore machinery
makes no attempt to understand the SQL being provided, it just uses it as a
subquery in the from clause.
Query hints, at least in the databases that I'm
I am sure it was just lack of scope; since the virtual tables can be any
SQL query - it was probably not obvious how to integrate a select hint?
If you have a join for example which select would you like to add the hint
to? Or would you like to create a subquery and do the select on the result?
Hi all,
Recently, a group of GeoServer users on HANA requested the possibility to
append hints to SQL queries. Luckily, there was already
SQLDialect#handleSelectHints(). So, I could just override the method in
HanaDialect and append the hints to the query, which I did in [GEOT-7230]
