pytibero 0.2.0

Unofficial Python DB-API 2.0 connector for Tibero

pytibero

Unofficial Python DB-API 2.0 connector for Tibero

pytibero provides a Pythonic DB-API 2.0 interface for Tibero databases. The current implementation uses pyodbc as the transport backend and wraps Tibero ODBC connectivity behind a clean, package-owned API surface.

This is an independent community project and is not officially supported by TmaxSoft. This project is not affiliated with TmaxSoft.

Why pytibero

• Python DB-API 2.0 compatible module surface
• Direct host/port or DSN-based Tibero ODBC connections
• Optional tbcli backend for Tibero's native client library path (with Decimal precision and chunked large-column reads)
• Explicit autocommit plus routed pyodbc.connect(...) keyword support
• Package-owned exception hierarchy and type constructors
• Safe access to common pyodbc connection metadata such as getinfo(...)
• Dockerized unit-test workflow with a 95% coverage target
• Docker-based end-to-end test harness for licensed Tibero environments

Installation

Python package

pip install pytibero

System requirements

• Python 3.10+
• pyodbc
• unixODBC or an equivalent ODBC manager
• A Tibero ODBC driver installed on the host or in the container

Quick Start

import pytibero

with pytibero.connect(
    host="localhost",
    port=8629,
    database="test",
    user="tibero",
    password="tmax",
) as conn:
    cursor = conn.cursor()
    cursor.execute("SELECT 1 FROM dual")
    print(cursor.fetchall())

DSN connection

import pytibero

conn = pytibero.connect(dsn="TIBERO_TEST", user="tibero", password="tmax")

Native tbcli backend

import pytibero

conn = pytibero.connect(
    host="localhost",
    port=8629,
    database="test",
    user="tibero",
    password="tmax",
    backend="tbcli",
    tbcli_library="/opt/tibero7/client/lib/libtbcli.so",
)

backend="tbcli" uses Tibero's native CLI library instead of pyodbc. This path is intended for environments where the vendor client library is available locally.

Advanced connection options

import pytibero

conn = pytibero.connect(
    host="localhost",
    user="tibero",
    password="tmax",
    autocommit=True,
    readonly=True,
    ansi=False,
    ApplicationName="pytibero-app",
)

print(conn.getinfo(17))

readonly, ansi, and similar pyodbc.connect(...) options are forwarded as native connect kwargs, while additional values such as ApplicationName stay in the ODBC connection string.

Testing

Unit tests in Docker

make test-docker

This runs the package test suite inside Docker and enforces a 95% coverage threshold.

End-to-end tests in Docker

export TIBERO_LICENSE_FILE=/abs/path/to/license.xml
make test-e2e-docker

The e2e flow expects a licensed Tibero Docker image and a valid license file. See docs/testing.md for the required environment variables.
