SQLean: all the missing SQLite functions

SQLite has very few functions compared to other DBMS. SQLite authors see this as a feature rather than a bug, because SQLite has extension mechanism in place.

There are a lot of SQLite extensions out there, but they are incomplete, inconsistent and scattered across the internet.

sqlean brings them all together, neatly packaged by domain modules and built for Linux, Windows and macOS.

Here is what we've got right now:

  • crypto: secure hashes
  • json1: JSON functions
  • math: math functions
  • re: regular expressions
  • stats: math statistics
  • text: string functions
  • unicode: Unicode support
  • vsv: CSV files as virtual tables

Download

There are precompiled binaries for every OS:

  • *.dll - for Windows
  • *.so - for Linux
  • *.dylib - for macOS

Binaries are 64-bit and require a 64-bit SQLite version. If you are using SQLite shell on Windows (sqlite.exe), its 64-bit version is available at https://github.com/nalgeon/sqlite.

Usage

CLI usage:

sqlite> .load ./stats
sqlite> select median(value) from generate_series(1, 100);

IDE usage:

select load_extension('/path/to/extension/stats');
select median(value) from generate_series(1, 100);

In-app usage:

import sqlite3

connection = sqlite3.connect(":memory:")
connection.enable_load_extension(True)
connection.load_extension("./stats.so")
connection.execute("select median(value) from generate_series(1, 100)")
connection.close()

You can specify any other supported extension instead of stats.
