sqlite implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine to query .sql files.

Getting started

To use sqlite, you must have a valid metadata file with a .db file extension, and an installed version of SQL. This tutorial assumes knowledge of the command line.

To start the sql engine, type:

sqlite3

The prompt will change, showing that the sqlite engine has been initialised. To open a metadata file, type:

.open filename.db

You can then display tables with:

.tables

Based on what is returned, you can then query the content of each table with commands such as:

SELECT * FROM users

You may want to have a more human-readable view of the data that is printed in the terminal, by organising the headings and columns:

.headers ON
.mode columns
