Someone please confirm: using SetCampaignInt and "nwnx&

[QuintellaRosa]

Someone please confirm:
1. Using SetCampaignXXXX and "nwnx" as DB name, scripts will save data on the SQL database instead of the game.
2. Does NWNX redirect the original SetCampaign functions to SetPersistent functions?
3. So, if I change SetPersitent functions inside nwnx_sql.nss, using SetCampaign will act as I want, right?
4. The "Expire" column will be checked only for a table called "pwdata"?

Thanks!
