You can specify a full path like /var/sqlite/myapp.db to choose where the database file is created. to populate and work with the database.īy default, SQLite creates data files in the current directory.

Within the CLI shell, you can then run commands like CREATE TABLE, INSERT etc. This will create a new database file tutorial.db in the current directory. open command when launching the sqlite3 CLI shell: $ sqlite3 tutorial.dbĮnter SQL statements terminated with a ' ' To create a new SQLite database, specify the database file name after the. Any type of data can be inserted into any column.

SQLite does not enforce data type constraints (apart from PRIMARY KEY column). SQLite does not have separate Boolean storage class – BOOLEAN values are stored as integers 0 (false) and 1 (true). SQLite supports common data types for storing data in tables: Overall, the SQL language itself is identical to other databases like MySQL, PostgreSQL etc. These allow configuring the CLI shell to suit your requirements. nullvalue – Set text to display for NULL values headers – Toggle display of column headers databases – List names of attached databases shell command to interactively run SQL statements if you are using the SQLite CLI shell.

DROP TABLE – Delete an entire table from the database.UPDATE – Modify existing data in a table.tables – List names of tables in the database Here are some of the most common SQLite commands: Once SQLite is integrated into your application, interacting with the database is done using SQL statements like any other database. After adding the library, you can start building applications with SQLite databases. Overall, integrating SQLite is straightforward for most programming languages and platforms. Docker Image – SQLite Docker image can be used to integrate SQLite into your Docker projects.IDE Extensions – Installing SQLite extensions on IDEs like Visual Studio, Xcode etc.have built-in modules to support SQLite databases.

SQLite is a great choice as an embedded database for local/client storage in software programs and mobile apps.

Full-featured – Supports SQL queries, triggers, views, transactions etc.

Reliable – Used in high-reliability applications like smartphones, browsers etc.

Small Footprint – Library size of less than 300 KB, database files in kilobytes to megabytes.

Cross-Platform – Available on all major operating systems.

Self-Contained – Contains entire database in a single disk file.

Transactional – Atomic, consistent, isolated, durable (ACID) transactions.

Zero Configuration – No setup or administration needed.

Serverless – No separate server process needed, reads and writes directly to disk files.

SQLite is the most widely deployed database in the world – it is used in most smartphones, web browsers, operating systems and many other applications.
