Connecting to SQLite from the command line

To connect to SQLite from the command line, follow these steps:

  1. Log in to your A2 Hosting account using SSH.
  2. At the command line, type the following command, replacing example.db with the name of the database file that you want to use:
    sqlite3 example.db
    The database filename can be anything you want. If the database file does not exist, SQLite creates it. If the database file already exists, SQLite opens the database contained in the file.

    • For SQLite show tables, type the following command at the sqlite> prompt:

What Is SQLite?

sqliteSQLite is a lightweight database management solution. It offers its users a high-performance, very dependable SQL database engine. SQLite's code is available within public domain making it free for use for every private or commercial purpose. SQLite has been built into every mobile device and almost every computer. In fact, SQLite is the world's most widely used database engine.

SQLite is a unique SQL solution because it doesn't require a separate server process. Instead, it reads and writes right on disk files. A disk file contains a comprehensive SQL database complete with multiple tables, views and triggers. As a cross-platform file format, you are able to copy between 32-bit and 64-bit storage systems.

SQLite is:

  • Serverless
  • Self-contained
  • Zero-configuration
  • Transactional

SQLite History

Software developer Dwayne Richard Hipp, while working for General Dynamics, wrote SQLite in early 2000 while on contract with the US Navy. SQLite was originally a Tcl extension. The goal of SQLite was to create a solution that didn't require a database management solution or have the need for a database administrator. Hipp wrote the SQLite syntax close to that of PostgreSQL.
