SQLite is one of the most widely used database engines in the world. It powers thousands of applications and mobile devices thanks to its lightweight nature and serverless architecture. In this comprehensive guide, we will look at how to install SQLite on different platforms.
Importance of SQLite in Modern Applications
SQLite is an in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. It is the most used database engine in the world, powering thousands of desktop, web and mobile applications.
The key advantages of SQLite that make it suitable for modern applications are:
- Lightweight – The entire database is contained in a single disk file on the host machine. This makes it very easy to manage and transport.
- Serverless – There is no client-server architecture. SQLite reads and writes directly to an ordinary disk file. This reduces latency and simplifies the system.
- Zero Configuration – There is no setup or administration needed for SQLite. This simplifies application development.
- Embedded – SQLite is perfect for embedding in end applications since it requires minimal memory footprint. This makes it ideal for mobile apps and IoT devices.
- ACID Compliant – SQLite offers full ACID (Atomicity, Consistency, Isolation, Durability) guarantees for transaction reliability.
- Cross-Platform – SQLite runs on most modern operating systems like Windows, Mac, Linux, iOS and Android. This allows developers to use a single database for multiple platforms.
In this article, we will go through the steps to install SQLite on different operating systems and platforms. We will also look at some additional tools and troubleshooting techniques.
What is SQLite?
Before we jump into the installation guide, let’s first briefly understand what SQLite is and its key features.
Introduction to SQLite
SQLite is a relational database management system contained in a compact C library. It implements most of the SQL 92 standard and provides CRUD (Create, Read, Update, Delete) operations for data manipulation.
SQLite is ACID-compliant and transactional, making it suitable for data applications that require reliability. It requires no configuration and stores the entire database in a single file on disk.
The SQLite source code is in the public domain, making it free to use for commercial and non-commercial purposes. Its design focuses on efficient data storage and retrieval operations.
Features and Advantages
Some of the notable features of SQLite include:
- Self-contained – Requires minimal dependencies so it is very easy to integrate SQLite into an application
- Serverless – There is no client-server architecture. SQLite reads and writes directly to ordinary disk files.
- Zero Config – There is no installation or setup required for SQLite. This simplifies development.
- ACID Compliant – SQLite offers full ACID guarantees for reliable transactions.
- Compact – The database is stored as a single cross-platform disk file. This also allows easy backups.
- Full-featured – Implements most of the SQL 92 standard including transactions, triggers, constraints, etc.
These features make SQLite an ideal choice as an embedded lightweight database for end applications. Next, we will look at some pre-installation checks.
Pre-Installation Checks
Before installing SQLite, it is good to check if it is already available on your system to avoid re-installation.
How to Check if SQLite is Already Installed
SQLite comes pre-installed on many operating systems and distributions. To check if it is already present, simply open the terminal (command prompt on Windows) and type sqlite3.
$ sqlite3 SQLite version 3.7.15.2 2013-01-09 11:53:05 Enter ".help" for instructions Enter SQL statements terminated with a ";" sqlite>If you see a response like above with the version number, it indicates SQLite is already installed and you can start using it right away.
Systems Where SQLite Comes Pre-installed
Here are some common systems where SQLite is available by default:
- Windows 10 – Windows 10 and later versions come with SQLite pre-installed.
- Mac OS – All modern macOS versions have a built-in SQLite installation.
- Linux – Most mainstream Linux distributions like Ubuntu, Fedora, CentOS, etc. include SQLite in their repository.
- Android – The Android OS uses SQLite as its default relational database to power apps.
- iOS – iOS devices come with SQLite pre-built into the OS.
So in many cases, you can start building SQLite apps without needing to install SQLite explicitly. Next, we will go through SQLite installation steps for different platforms.
SQLite Installation on Windows
If SQLite is not already present on your Windows OS, you can easily download and install it. Here is the complete guide:
Downloading the SQLite ZIP File
First, visit the official SQLite Download page and scroll down to the Windows section. You will find two SQLite precompiled binary ZIP files:
sqlite-tools-win32-*.zip– 32-bit version for 32-bit Windowssqlite-tools-win64-*.zip– 64-bit version for 64-bit Windows
Download the appropriate ZIP file based on whether you have a 32-bit or 64-bit machine.
Extracting and Setting up the Environment Variables
Once the ZIP is downloaded, extract it to a folder on your Windows computer. For example, C:\sqlite.
Next, we need to add the sqlite folder to the PATH environment variable. This allows running SQLite from any directory.
- Go to Control Panel > System > Advanced System Settings
- Click on Environment Variables
- Under System Variables find the PATH variable and click on it to edit
- Click on New and add the path
C:\sqliteto the PATH variable - Click OK to save the changes and close all windows
Verifying the Installation through the Command Line
To confirm that the installation was successful, open the command prompt and run the command:
sqlite3 --versionThis should print the version of SQLite installed, confirming it is now available for use.
That completes the installation process for SQLite on Windows. Next, we will see how to install it on Mac OS.
SQLite Installation on Mac
Modern macOS versions come with SQLite pre-installed but if you need to reinstall or upgrade SQLite, follow these instructions:
Checking for Pre-installed SQLite
As mentioned earlier, open the Terminal app and run sqlite3 to check if SQLite already exists:
$ sqlite3 SQLite version 3.31.1 2020-01-27 19:55:54 Enter ".help" for usage hints. Connected to a transient in-memory database. Use ".open FILENAME" to reopen on a persistent database. sqlite>If you see the version and help message, SQLite is already installed. You can skip the installation steps.
Downloading and Extracting the ZIP File
If SQLite needs to be installed/upgraded, download the SQLite ZIP file for Mac OS from the official website and extract it.
For example, unzip it to the /usr/local/sqlite folder. This will create a bin folder inside it that contains the SQLite binary executable and shell.
Running SQLite through the Terminal
To confirm the installation, open the Terminal app and run the sqlite3 command:
$ sqlite3 SQLite version 3.31.1 2020-01-27 19:55:54 Enter ".help" for usage hints. Connected to a transient in-memory database. Use ".open FILENAME" to reopen on a persistent database. sqlite>If it runs successfully, your SQLite installation on macOS is complete. You can now start building database-driven applications using it.
Next, we will look at installing SQLite on Linux OS.
SQLite Installation on Linux
Linux distributions include SQLite as a package that can be installed via the native package manager tool.
Installing SQLite through Package Managers
Here are the commands to install SQLite using the package managers on some common Linux distros:
Debian / Ubuntu
