jcfrank / erlang-sqlite3

Sqlite gen_server port for Erlang. Creates, reads and writes to sqlite database.

Erlang wrapper for SQLite3

This library allows you to work with SQLite3 databases from Erlang.

It is compatible with Windows and Linux, and should probably work on other OSes as well.

See also esqlite for an alternative library.

Requirements

Erlang/OTP R14B or later is required (tested up to 17.3 at this writing), and SQLite 3 minimum version is 3.6.1.

Compiling

Linux

1. Install SQLite3 by running sudo apt-get install sqlite3 or the equivalent for your package manager, or by compiling from the source.

2. make.

Cross-compiling

If you want to use erlang-sqlite3 on an embedded device, it can be cross-compiled.

1. Cross-compile SQLite3 and Erlang.

2. Change variables and paths in rebar.cross_compile.config.sample to the desired values and rename it to rebar.cross_compile.config.

3. make cross_compile.

Windows with MS Visual C++

To build both SQLite3 and sqlite3-erlang:

1. If MSVC tools (cl, link, etc.) are not in the path, run vcvars32.bat or vcvars64.bat depending on whether you use 32-bit or 64-bit Erlang. build_port_win32.bat and build_port_win64.bat have the standard paths for VC10.0.

2. nmake.

Alternately, you can use prebuilt versions of sqlite3.dll and sqlite3.def. To make sqlite3.lib, use lib /def:sqlite3.def. Then remove sqlite3.dll and sqlite3.lib targets from Makefile and do as above.

Potential compilation problems

• If SQLite was built with SQLITE_OMIT_LOAD_EXTENSION option, you'll need to undefine ERLANG_SQLITE3_LOAD_EXTENSION macro in <c_src/sqlite3_drv.h>.

Running the test suite

Linux

make test

Windows

1. nmake tests

2. If you get the error "Error loading sqlite3_drv: The specified module could not be found", this is because sqlite3.dll isn't in the search path.

Example usage

See tests test/sqlite3_test.erl for a starting point. On Windows note that sqlite3.dll must be in your application's working directory or somewhere in the DLL search path.
