macss-modular-api-sqlserver

Official MACSS SQL Server integration package for Python.

Quick start

from modular_api_sqlserver import DbClient, DbCommand, DbCommandKind, DbConnectionSettings

settings = DbConnectionSettings.from_environment()

client = DbClient(
    settings=settings,
    session_provider=my_session_provider,
    command_executor=my_command_executor,
    transaction_runner=my_transaction_runner,
)

result = client.scalar(
    DbCommand(
        kind=DbCommandKind.SCALAR,
        text="select count(*) from users",
        label="users.count",
    )
)

if result.is_success:
    print(result.value.value)
else:
    print(result.failure.message)

See example/example.py for a complete in-memory wiring sample.

What this package provides

• normalized SQL Server connection defaults and redacted summaries
• engine-agnostic DbClient, DbRepository, and transaction contracts
• explicit lease ownership semantics for package-owned and application-owned sessions
• health contributor and GraphQL support bundle for higher-level integrations
• the application supplies the driver binding (adapter) for its chosen engine and driver

This package is contracts-only by design and will never ship a driver binding; you choose your engine and driver and provide the adapter. See ADR-0004.
