This library takes the SQLite module from Python 3 and packages it as a separately-installable module.

This may be useful for creating SQLite modules capable of working with other versions of SQLite (via the amalgamation option).

Additional features:

  • User-defined window functions (requires SQLite >= 3.25)
  • Flags and VFS an be specified when opening connection
  • Incremental BLOB I/O, bpo-24905
  • Improved error messages, bpo-16379
  • Simplified detection of DML statements via sqlite3_stmt_readonly.
  • Sqlite native backup API (also present in standard library 3.7 and newer).

A completely self-contained binary package (wheel) is available for versions 0.4.1 and newer as pysqlite3-binary. This package contains the latest release of SQLite compiled with numerous extensions, and requires no external dependencies.

Building with System SQLite

If you intend to use the system SQLite, you can install with:

$ pip install pysqlite3

Alternatively you can clone or download the repo and use to build pysqlite3 linked against the system SQLite:

$ python build

Building a statically-linked library

To build pysqlite3 statically-linked against a particular version of SQLite, you need to obtain the SQLite3 source code and copy sqlite3.c and sqlite3.h into the source tree.

# Download the latest release of SQLite source code and build the source
# amalgamation files (sqlite3.c and sqlite3.h).
$ wget \
    -O sqlite.tar.gz
$ tar xzf sqlite.tar.gz
$ cd sqlite/
$ ./configure
$ make sqlite3.c

# Copy the sqlite3 amalgamation files into the root of the pysqlite3 checkout
# and run build_static + build:
$ cp sqlite/sqlite3.[ch] pysqlite3/
$ cd pysqlite3
$ python build_static build

You now have a statically-linked, completely self-contained pysqlite3.

Using the binary package

A binary package (wheel) is available for linux with a completely self-contained pysqlite3, statically-linked against the most recent release of SQLite with many features/extensions enabled.

$ pip install pysqlite3-binary
