alt-python-pydbc-core
Core abstraction layer for pydbc — the uniform database access library for Python.
This package provides the ABCs, registries, and generic helpers that all pydbc driver packages depend on. You do not normally install this package directly. Install the driver package for your database; alt-python-pydbc-core is pulled in automatically as a dependency.
# Install the driver for your database — core is a transitive dependency
uv add alt-python-pydbc-sqlite # SQLite
uv add alt-python-pydbc-pg # PostgreSQL
uv add alt-python-pydbc-mysql # MySQL / MariaDB
uv add alt-python-pydbc-mssql # SQL Server
What this package provides
ABCs (Abstract Base Classes)
| Class | Purpose |
|---|---|
Driver |
Abstract base for all pydbc drivers |
Connection |
Abstract connection handle |
Statement |
Execute arbitrary SQL |
PreparedStatement |
Execute pre-compiled SQL with bound parameters |
ResultSet |
Row access after a query |
DataSource |
Connection factory abstraction |
ConnectionPool |
Connection pool abstraction |
DriverManager
Central registry that maps connection URLs to registered drivers. Driver packages
self-register at import time by calling DriverManager.register_driver().
import pydbc_sqlite # registers SQLiteDriver
from pydbc_core import DriverManager
conn = DriverManager.get_connection("pydbc:sqlite::memory:")
stmt = conn.create_statement()
rs = stmt.execute_query("SELECT 42 AS n")
print(rs.rows) # [(42,)]
conn.close()
GenericDbApiDriver
A reusable base driver that wraps any DB-API 2.0 module. Driver packages typically subclass this; it handles connection lifecycle, cursor management, and paramstyle normalisation automatically.
DataSource helpers
| Class | When to use |
|---|---|
SingleConnectionDataSource |
Tests and scripts that need one persistent connection |
PooledDataSource |
Servers and applications that need a connection pool |
NamedParameterDataSource |
Convenience wrapper with named-parameter query/update methods |
ParamstyleNormalizer
Rewrites SQL written with ? (positional) or :name (named) placeholders to
whatever the underlying DB-API 2.0 driver expects (%s, %(name)s, :1, etc.).
This means you write SQL once and it works against any driver.
