How to create a trigger to send any new form sent through ODK to be sent to SQL server as well?

I'm digging to know how to create a trigger to send or copy any coming
survey through ODK to be sent to SQL server as well. Also, I'm still
searching if there is a fast mean to move all old records in ODK server to
SQL server. I saw some posts about this, but most people confirmed that ODK
cannot deal directly with SQL, please share with me your thoughts on this.
