dblab

Interactive client for PostgreSQL, MySQL and SQLite3.

Overview

dblab is a fast and lightweight interactive terminal based UI application for PostgreSQL, MySQL and SQLite3, written in Go and works on OSX, Linux and Windows machines. Main idea behind using Go for backend development is to utilize ability of the compiler to produce zero-dependency binaries for multiple platforms. dblab was created as an attempt to build very simple and portable application to work with local or remote PostgreSQL/MySQL/SQLite3 databases.

Features

• Cross-platform support OSX/Linux/Windows 32/64-bit
• Simple installation (distributed as a single binary)
• Zero dependencies

Installation

Homebrew

It works with Linux, too.

$ brew install danvergara/tools/dblab

Or

$ brew tap danvergara/tools
$ brew install dblab

Binary Release (Linux/OSX/Windows)

You can manually download a binary release from the release page.

Automated install/update, don't forget to always verify what you're piping into bash:

curl https://raw.githubusercontent.com/danvergara/dblab/master/scripts/install_update_linux.sh | bash

The script installs downloaded binary to /usr/local/bin directory by default, but it can be changed by setting DIR environment variable.

Help

dblab is a terminal UI based interactive database client for Postgres, MySQL and SQLite3.

Usage:
  dblab [flags]
  dblab [command]

Available Commands:
  help        Help about any command
  version     The version of the project

Flags:
      --config          get the connection data from a config file (default is $HOME/.dblab.yaml or the current directory)
      --db string       Database name
      --driver string   Database driver
  -h, --help            help for dblab
      --host string     Server host name or IP
      --limit int       Size of the result set from the table content query (default 100)
      --pass string     Password for user
      --port string     Server port
      --ssl string      SSL mode
  -u, --url string      Database connection string
      --user string     Database user

Use "dblab [command] --help" for more information about a command.

Usage

You can start the app passing no flags or parameters, you'll be asked for connection data instead.

$ dblab --host localhost --user myuser --db users --pass password --ssl disable --port 5432 --driver postgres --limit 50
$ dblab --db path/to/file.sqlite3 --driver sqlite3

Connection URL scheme is also supported:

$ dblab --url postgres://user:password@host:port/database?sslmode=[mode]
$ dblab --url mysql://user:password@tcp(host:port)/db
$ dblab --url file:test.db?cache=shared&mode=memory

Now, you can use a configuration file to make a connection to the database.

$ dbladb --config

dblab is going to look for a file called .dblab.yaml. For now, the only two places where you can drop a config file are $HOME ($HOME/.dblab.yaml) and the current directory where you run the command line tool.

.dblab.yaml example:

database:
  host: "localhost"
  port: 5432
  db: "users"
  password: "password"
  user: "postgres"
  driver: "postgres"
limit: 50

Or for sqlite3:

database:
  db: "path/to/file.sqlite3"
  driver: "sqlite3"

Only the host and ssl fields are optionals. 127.0.0.1 and disable, respectively.

If the query panel is active, type the desired query and press Ctrl+Space to see the results on the rows panel below. Otherwise, you might me located at the tables panel, then you can navigate by using the arrows Up and Down (or the keys k and j respectively). If you want to see the rows of a table, press Enter. To see the the schema of a table, locate yourself on the rows panel and press Ctrl+S to switch to the structure panel, then switch Ctrl+S to switch back. The same can be achieved for the constraints view by pressing Ctrl+F to go back and forth between the rows and the constraints panels.

Now, there's a menu to navigate between hidden views by just clicking on the desired options:

As you may have noticed, navigation has already been added, so every time you query the content of a listed table, the result set is going to be paginated. This allows to the user dealing with large tables, optimizing resources. Just hit the BACK and NEXT buttons to go back and forth.
