miu-db 0.1.4

Fast terminal SQL across your databases.

miu-db

Fast terminal SQL across your databases.
Pick a connection, write SQL, inspect results, stay in your shell.

miu-db is part of the miumono umbrella: small, focused terminal-native tools that are easy to install, easy to run locally, and predictable in CI.

Quick Start

Install from PyPI:

uv tool install miu-db
miu-db

Try the TUI without a real database:

miu-db --mock=sqlite-demo

Run one query from the CLI:

miu-db query -c local -q "select 1"

Source Install

For local development, install this checkout in editable mode. Code edits apply the next time you run miu-db.

cd /Users/vanducng/git/personal/miu-db
uv tool install --force --editable ".[all]"
miu-db --mock=sqlite-demo

Re-run the install command after changing dependencies, entry points, or pyproject.toml.

Connections

Save local connections:

miu-db connections add sqlite --name local --file-path ./app.db
miu-db connections add postgresql --name pg --server localhost --database app --username app
miu-db connections add mysql --name mysql --server localhost --database app --username app

Connect without saving:

miu-db connect sqlite --file-path ./app.db
miu-db postgresql://user:pass@localhost:5432/app
miu-db mysql://root@localhost/app

Manage saved connections:

miu-db connections list
miu-db connections delete local

Passwords are stored in the OS keyring under the miu-db service when possible.

Capabilities

• Terminal UI with explorer, SQL editor, and results grid.
• Vim-style normal/insert modes.
• Per-connection query history.
• Fuzzy filtering over result rows.
• Saved connections with keyring-backed passwords.
• Docker database discovery.
• SSH tunnels.
• Driver install hints when an adapter dependency is missing.

SQLite works out of the box. Optional adapters cover PostgreSQL, MySQL, SQL Server, MariaDB, Oracle, DuckDB, ClickHouse, Snowflake, BigQuery, Athena, Spanner, Turso, D1, Firebird, Redshift, Db2, HANA, Teradata, Trino, Presto, Flight SQL, Impala, SurrealDB, osquery, and more.

Keys

Key	Action
i	Insert mode
Esc	Normal mode
e / q / r	Focus explorer / query / results
Enter	Run statement under cursor
h	Query history
s	Select top rows from table
v	View selected cell
y / Y	Copy cell / row
<space>	Command menu
?	Help
Ctrl+Q	Quit

Config

This is a brand-new miu-db app, not a legacy config alias.

• config: ~/.config/miu/db
• override: MIU_DB_CONFIG_DIR
• env vars: MIU_DB_*
• keyring service: miu-db

miu-db config edit
miu-db config show-keymap

On first run, miu-db copies missing files from ~/.config/sqlit into ~/.config/miu/db so existing saved connections keep working. Existing files in the new location are never overwritten.

Develop

uv sync --all-extras --dev
uv run miu-db --mock=sqlite-demo
uv run pytest tests/unit/test_config_dir_resolution.py -q
uv run pytest tests/test_sqlite.py -q --timeout=60

Build the package:

uv run python -m build
