How to execute direct SQL statements on a db shard?

[luca.fin...@centervue.com]

Hi all, 

how can I execute direct SQL statements over a db shard?

I made some very quick and easy tests but it seems to me that it is not possible to, say, execute something like this:

boss_db:execute("select * from sharded_table"),

as boss_db apparently always performs the query on the 'default' database. 

Any hints on how to do this? 

Thank you in advance

Luca.
