Hi,

For Sqilte3 C API, I would use sqlite3_last_insert_rowid. How to get this id when using ActiveRecord after insert a new record? I use following way to insert a new record :

Section.new |s|
     s.a = 1
     s.b = 2
     #I expected the return value of save to be the last_insert_id, but it is NOT
     s.save   
end
