SQLite3-OCaml is an OCaml library with bindings to the SQLite3 client API. Sqlite3 is a self-contained, serverless, zero-configuration, transactional SQL database engine with outstanding performance for many use cases.
These bindings are written in a way that enables a friendly coexistence with
the old (version 2) SQLite and its OCaml wrapper ocaml-sqlite.
The API in file lib/sqlite3.mli is fully documented, and HTML-documentation
can be built using make doc and installed with this distribution. It can
also be found online.
SQLite3 has its own online documentation.
The test-directory in this distribution contains a few simple examples
for testing various features of this library.
SQLite3-OCaml depends on pkg-config to locate and compile against an
SQLite3 library.
If the SQLite3 version is larger than or equal to 3.3.7, it is assumed that it supports Run-Time Loadable Extensions. If this feature has been explicitly disabled in the library, the build will fail with:
Undefined symbols for architecture ...:
"_sqlite3_enable_load_extension", referenced from:
_caml_sqlite3_enable_load_extension in libsqlite3_stubs.a(sqlite3_stubs.o)
(maybe you meant: _caml_sqlite3_enable_load_extension)
-
You can check if your library is missing loadable extensions by searching it for the string
OMIT_LOAD_EXTENSION. -
If you need to change where
pkg-configwill look for the SQLite3 library, set thePKG_CONFIG_PATHenvironment variable to the new directory.

Enrico Tassi contributed support for user-defined scalar functions.
-
Markus Mottl rewrote Christian's bindings for Jane Street Holding, LLC to clean up a few things and to make it perform better in multi-threaded environments.
-
Christian Szegedy wrote the initial release for SQLite version 3.
-
Mikhail Fedotov wrote ocaml-sqlite for SQLite version 2. His bindings served as a reference for this wrapper, but sqlite3 is written completely from scratch since the C interface changed significantly.
