Constraint errors (e.g. foreign keys) can fail in the fetch phase of a query. The library did not support error handling in the fetch phase yet.
Esqlite 
An Erlang nif library for sqlite3.
Introduction
This library allows you to use the accelent sqlite engine from erlang. The library is implemented as a nif library, which allows for the fastest access to a sqlite database. This can be risky, as a bug in the nif library or the sqlite database can crash the entire Erlang VM. If you do not want to take this risk, it is always possible to access the sqlite nif from a separate erlang node.
Special care has been taken not to block the scheduler of the calling process. This is done by handling all commands from erlang within a lightweight thread. The erlang scheduler will get control back when the command has been added to the command-queue of the thread.
