sqlean.py

This package provides an SQLite Python wrapper bundled with sqlean extensions. It's a drop-in replacement for the standard library's sqlite3 module.

The project is no longer maintained.

pip install sqlean.py

import sqlean

# enable all extensions
sqlean.extensions.enable_all()

# has the same API as the default sqlite3 module
conn = sqlean.connect(":memory:")
conn.execute("create table employees(id, name)")

# and comes with sqlean extensions
cur = conn.execute("select median(value) from generate_series(1, 99)")
print(cur.fetchone())
# (50.0,)

conn.close()

Extensions

sqlean.py contains essential SQLite extensions:

• crypto: Hashing, encoding and decoding data
• define: User-defined functions and dynamic SQL
• fileio: Reading and writing files
• fuzzy: Fuzzy string matching and phonetics
• ipaddr: IP address manipulation
• regexp: Regular expressions
• stats: Math statistics
• text: String functions
• time: High-precision date/time
• uuid: Universally Unique IDentifiers
• vsv: CSV files as virtual tables

Installation

pip install sqlean.py

Note that the package name is sqlean.py, while the code imports are just sqlean. The sqlean package name was taken by some zomby project and the author seemed to be unavailable, so I had to add the .py suffix.

A binary package (wheel) is available for the following operating systems:

• Linux (x86_64/aarch64)
• macOS (x86_64/arm64)

Unfortunately, there are no wheels available for Windows.

Usage

All extensions are disabled by default. You can still use sqlean as a drop-in replacement for sqlite3:

import sqlean as sqlite3

conn = sqlite3.connect(":memory:")
cur = conn.execute("select 'sql is awesome'")
print(cur.fetchone())
conn.close()

To enable all extensions, call sqlean.extensions.enable_all() before calling connect():

import sqlean

sqlean.extensions.enable_all()

conn = sqlean.connect(":memory:")
cur = conn.execute("select median(value) from generate_series(1, 99)")
print(cur.fetchone())
conn.close()

To enable specific extensions, call sqlean.extensions.enable():

import sqlean

sqlean.extensions.enable("stats", "text")

conn = sqlean.connect(":memory:")
cur = conn.execute("select median(value) from generate_series(1, 99)")
print(cur.fetchone())
conn.close()
