Overview

Currently our adapter is named the same as what AR5 names its adapter. We will need to get this changed at some point so this can be a unique name and we can extend activerecord ActiveRecord::ConnectionAdapters::SQLite3Adapter. Once we can do that we can remove the module SQLite3 above and remove a majority of this file.

#exec_insert(sql, name = nil, binds = [], pk = nil, sequence_name = nil) ⇒ Object

SQLite driver doesn't support all types of insert statements with executeUpdate so make it act like a regular query and the ids will be returned from #last_inserted_id example: INSERT INTO "aircraft" DEFAULT VALUES
