Gitqlite: Query Git Repositories with SQL

Go Report Card

gitqlite is a tool for running SQL queries on git repositories.
It implements SQLite virtual tables and uses go-git.
It’s meant for ad-hoc querying of git repositories on disk through a common interface (SQL), as an alternative to patching together various shell commands.


go install -v -tags=sqlite_vtable github.com/augmentable-dev/gitqlite

Will use the go tool chain to install a binary to $GOBIN.

GOBIN=$(pwd) go install -v -tags=sqlite_vtable github.com/augmentable-dev/gitqlite

Will produce a binary in your current directory.

TODO: more installation instructions


gitqlite -h

Will output the most up to date usage instructions for your version of the CLI.
Typically the first argument is a SQL query string:

gitqlite "SELECT * FROM commits"

Your current working directory will be used as the path to the git repository to query by default.
Use the --repo flag to specify an alternate path, or even a remote repository reference (http(s) or ssh).
gitqlite will clone the remote repository to a temporary directory before executing a query.

You can also pass a query in via stdin:

cat query.sql | gitqlite

By default, output will be an ASCII table.
Use --format json or --format csv for alternatives.
See -h for all the options.



Similar to git log, the commits table includes all commits in the history of the currently checked out commit.

Column Type
message TEXT
summary TEXT
author_name TEXT
author_email TEXT
author_when DATETIME
committer_name TEXT
committer_email TEXT
committer_when DATETIME
parent_id TEXT
parent_count INT
tree_id TEXT
additions INT
deletions INT


The files table iterates over ALL the files in a commit history, by default from what’s checked out in the repository.
The full table is every file in every tree of a commit history.
Use the commit_id column to filter for files that belong to the work tree of a specific commit.

Column Type
commit_id TEXT
tree_id TEXT
name TEXT
mode TEXT
type TEXT
contents TEXT


Column Type
name TEXT
type TEXT
hash TEXT

Example Queries

This will return all commits in the history of the currently checked out branch/commit of the repo.

Return the (de-duplicated) email addresses of commit authors:

SELECT DISTINCT author_email FROM commits

Return the commit counts of every author (by email):

SELECT author_email, count(*) FROM commits GROUP BY author_email ORDER BY count(*) DESC

Same as above, but excluding merge commits:

SELECT author_email, count(*) FROM commits WHERE parent_count < 2 GROUP BY author_email ORDER BY count(*) DESC

This is an expensive query.
It will iterate over every file in every tree of every commit in the current history:

Outputs the set of files in the tree of a certain commit:

SELECT * FROM files WHERE commit_id='some_commit_id'

Same as above if you just have the commit short id:

SELECT * FROM files WHERE commit_id LIKE 'shortened_commit_id%'

Returns author emails with lines added/removed, ordered by total number of commits in the history:

SELECT count(*) AS commits, SUM(additions) AS additions, SUM(deletions) AS  deletions, author_email FROM commits GROUP BY author_email ORDER BY commits

Returns commit counts by author, broken out by day of the week:

    count(*) AS commits,
    count(case when strftime('%w',author_when)='0' then 1 end) as sunday,
    count(case when strftime('%w',author_when)='1' then 1 end) as monday,
    count(case when strftime('%w',author_when)='2' then 1 end) as tuesday,
    count(case when strftime('%w',author_when)='3' then 1 end) as wednesday,
    count(case when strftime('%w',author_when)='4' then 1 end) as thursday,
    count(case when strftime('%w',author_when)='5' then 1 end) as friday,
    count(case when strftime('%w',author_when)='6' then 1 end) as saturday,
FROM commits GROUP BY author_email ORDER BY commits
