I come back to this topic which is very problematic for me. The manner which I use permit me to read/save null values in database. But in fact, it's "null" string values that are stored in db. So, there is no constraint validation possible with that. Even worse, foreign key constraint can failed if you want to put a null foreign key since it's not really a null value....
I don't understand why query execution can take Object[] as parameter while it's converted to String[]. Why can't we inject object in the query and not string as params ??? Thanks !
