Install

SQLLoad installs from PyPI. Install it as a tool with uv:

uv tool install sqlload
sqlload --version

$ sqlload --version
sqlload 0.32.0

Choose a package

Two packages provide the same sqlload command. Install only one of them, because both provide a sqlload command.

Package	What it is	Python sources
sqlload	A native Python extension. Each platform has one wheel, built for Python’s stable ABI (abi3), which runs on every CPython from 3.10. Its sqlload command runs the loader in the same process as your Python sources.	Yes
sqlload-cli	The same command as a standalone executable, without Python.	No

Use sqlload if any table is defined in Python (Python sources). Use sqlload-cli where Python isn’t available and every source is declared in sqlload.toml.

uv tool install sqlload-cli

With pip, in a virtual environment:

pip install sqlload

Both packages are released for:

Platform	Architectures
Linux (glibc 2.28 or newer)	x86_64, aarch64
macOS 11 or newer	arm64, x86_64 (Intel)
Windows 10 or newer, Windows Server 2019 or newer	x86_64

Use it from Python

The sqlload package also imports as a library, for declaring Python sources:

import sqlload as sl

print(sl.__version__)
print(sl.executable())  # the sqlload command installed alongside the package

See the Python API.
