[sqlite] Using SQL and direct BTree interface to SQLite

[Brian Roe]

Hello.

I'm interested in using SQLite both at the SQL and BTree levels in an 
application.  That is, I would like to create tables and be able to run 
queries using SQL while also inserting into, querying and updating 
tables directly via the BTree-level C API calls (thus bypassing the SQL 
subsystem entirely).  Is there any information on how I can accomplish 
this without corrupting data, confusing SQLite, etc?  If no 
documentation currently exists on this, I would be grateful for any 
pointers from those who are familiar with the guts of SQLite.

Thanks,
Brian
