Tool for generating demo SQLite databases

Installation

Install this plugin using pip:

$ pip install sqlite-generate

Usage

To generate a SQLite database file called data.db with 10 randomly named tables in it, run the following:

sqlite-generate data.db

You can see a demo of the database generated using this command running in Datasette at https://sqlite-generate-demo.datasette.io/

You can use the --tables option to generate a different number of tables:

sqlite-generate data.db --tables 20

By default each table will contain a random number of rows between 0 and 200. You can customize this with the --rows option:

sqlite-generate data.db --rows 20

This will insert 20 rows into each table.

sqlite-generate data.db --tables 500,2000

This inserts a random number of rows between 500 and 2000 into each table.

Each table will have 5 columns. You can change this using --columns:

sqlite-generate data.db --columns 10

You can control the random number seed used with the --seed option. This will result in the exact same database file being created by multiple runs of the tool:

sqlite-generate data.db --seed=myseed

Development

To contribute to this tool, first checkout the code. Then create a new virtual environment:

cd sqlite-generate
python -mvenv venv
source venv/bin/activate

Or if you are using pipenv:

pipenv shell

Now install the dependencies and tests:

pip install -e '.[test]'

To run the tests:

pytest
