In the context of .NET development, SQLite source code serves as an excellent choice for integrating a reliable database solution control into your system applications. This article will delve into the world of SQLite transactions, exploring its features, advantages, and how to use it in your .NET projects effectively.

How to Use SQLite in C#

1. Download SQLite library
2. Create a database and insert the data
3. Read using reader
4. Use SQLite using Entity Framework and LINQ query method
5. Generate PDF Report using IronPDF

What is SQLite?

SQLite is a popular open-source database engine that can be embedded in applications without requiring a separate server component. It is fast, reliable, and cross-platform. SQLite can be used with .NET project applications through various libraries that provide ADO.NET interfaces. One of these libraries is Microsoft.Data.SQLite. This allows you to use SQLite as a data source for your .NET applications, whether they are Console, Desktop, Web, or Mobile. You can also use Entity Framework Core to perform object-relational mapping and query your SQLite database using LINQ.

This article shows you how to use Microsoft.Data.Sqlite to develop, connect, and manipulate an SQLite in a .NET Console Application. You will learn how to:

• Install the Microsoft.Data.Sqlite NuGet package
• Create a SQLite connection and execute SQL commands
• Create and populate tables using data readers and parameters
• Query data using data readers
• Implement EntityFramework Core
• Query data using LINQ
• Generate PDF Report

Installing the SQLite Library

To use Microsoft.Data.Sqlite, you need to install the NuGet package that contains the library and its dependencies. You can do this using the Visual Studio Package Manager, the .NET Core CLI, or any other tool that supports NuGet. This article will use the Package Manager to create a Console Application and install Microsoft.Data.Sqlite. To do this, open a Package Manager Console and run the following commands:

Install-Package Microsoft.Data.Sqlite

The above command will install the package as shown below.

Creating SQLite Database

To work with a SQLite database, you need to create a SQLiteConnection object that represents the connection to the database file. You can specify the file name and other options in the connection. If the file does not exist, it will be created automatically. For example, the below program creates a connection to a database file named employee.db in the current directory:

using (var connection = new SqliteConnection("Data Source=employee.db"))
{
  connection.Open();
  // ...
}

using (var connection = new SqliteConnection("Data Source=employee.db"))
{
  connection.Open();
  // ...
}

Using connection = New SqliteConnection("Data Source=employee.db")
  connection.Open()
  ' ...
End Using

The using statement ensures that the connection is closed and disposed of when it goes out of scope. To execute SQL commands, you need to create a SQLiteCommand object and associate it with the connection. You can set the CommandText property to the SQL statement you want to execute, and optionally add parameters to the Parameters collection. You can then call one of the methods of the SQLiteCommand object to execute the command, such as ExecuteNonQuery, ExecuteScalar, or ExecuteReader.

Create Table in SQLite

The following code creates a table named Employee using the ExecuteNonQuery method:

using (var connection = new SqliteConnection("Data Source=employee.db"))
{
    connection.Open();
    var command = connection.CreateCommand();
    command.CommandText = @" CREATE TABLE Employee (
        Id INTEGER PRIMARY KEY,
        FirstName TEXT NOT NULL,
        LastName TEXT NOT NULL,
        DESIGNATION TEXT NOT NULL )";
    command.ExecuteNonQuery();
}

using (var connection = new SqliteConnection("Data Source=employee.db"))
{
    connection.Open();
    var command = connection.CreateCommand();
    command.CommandText = @" CREATE TABLE Employee (
        Id INTEGER PRIMARY KEY,
        FirstName TEXT NOT NULL,
        LastName TEXT NOT NULL,
        DESIGNATION TEXT NOT NULL )";
    command.ExecuteNonQuery();
}

Using connection = New SqliteConnection("Data Source=employee.db")
	connection.Open()
	Dim command = connection.CreateCommand()
	command.CommandText = " CREATE TABLE Employee (
        Id INTEGER PRIMARY KEY,
        FirstName TEXT NOT NULL,
        LastName TEXT NOT NULL,
        DESIGNATION TEXT NOT NULL )"
	command.ExecuteNonQuery()
End Using

Insert Data into Table

To insert data into a table, you can use the same SQLiteCommand object and set the CommandText property to an INSERT statement. For example, the following code inserts three rows into the Employee table.

using (var connection = new SqliteConnection("Data Source=employee.db"))
{
    var command = connection.CreateCommand();
    StringBuilder builder = new StringBuilder();
    builder.Append("INSERT INTO Employee VALUES(1, 'John', 'Sami', 'CEO');");
    builder.Append("INSERT INTO Employee VALUES(2, 'David', 'Watson', 'Software Engineer');");
    builder.Append("INSERT INTO Employee VALUES(3, 'Victor', 'Khan', 'Content Writer');");
    connection.Open();
    command.CommandText = builder.ToString();
    command.ExecuteNonQuery();
}

using (var connection = new SqliteConnection("Data Source=employee.db"))
{
    var command = connection.CreateCommand();
    StringBuilder builder = new StringBuilder();
    builder.Append("INSERT INTO Employee VALUES(1, 'John', 'Sami', 'CEO');");
    builder.Append("INSERT INTO Employee VALUES(2, 'David', 'Watson', 'Software Engineer');");
    builder.Append("INSERT INTO Employee VALUES(3, 'Victor', 'Khan', 'Content Writer');");
    connection.Open();
    command.CommandText = builder.ToString();
    command.ExecuteNonQuery();
}

Using connection = New SqliteConnection("Data Source=employee.db")
	Dim command = connection.CreateCommand()
	Dim builder As New StringBuilder()
	builder.Append("INSERT INTO Employee VALUES(1, 'John', 'Sami', 'CEO');")
	builder.Append("INSERT INTO Employee VALUES(2, 'David', 'Watson', 'Software Engineer');")
	builder.Append("INSERT INTO Employee VALUES(3, 'Victor', 'Khan', 'Content Writer');")
	connection.Open()
	command.CommandText = builder.ToString()
	command.ExecuteNonQuery()
End Using

Read Data from SQLite

To read data from a table, you can use the ExecuteReader method of the SQLiteCommand object and set the CommandText property to a SELECT statement. This will return an SQLiteDataReader object that allows you to iterate over the rows and access the values by column name or index. You can use the Read method to move to the next row, and the GetXXX method to get the values as the appropriate data type. For example, the following code reads all the rows from the Employee table and prints them to the console:

using (var connection = new SqliteConnection("Data Source=employee.db"))
{
    var command = connection.CreateCommand();
    command.CommandText = @"SELECT * FROM Employee";
    connection.Open();
    using (var reader = command.ExecuteReader())
    {
        while (reader.Read())
        {
            var id = reader.GetInt32(0);
            string firstName = reader.GetString(1);
            string lastName = reader.GetString(2).ToString();
            string designation = reader.GetString(3).ToString();
            Console.WriteLine($"{id}: {firstName} - {lastName} - {designation}");
        }
    }
}

using (var connection = new SqliteConnection("Data Source=employee.db"))
{
    var command = connection.CreateCommand();
    command.CommandText = @"SELECT * FROM Employee";
    connection.Open();
    using (var reader = command.ExecuteReader())
    {
        while (reader.Read())
        {
            var id = reader.GetInt32(0);
            string firstName = reader.GetString(1);
            string lastName = reader.GetString(2).ToString();
            string designation = reader.GetString(3).ToString();
            Console.WriteLine($"{id}: {firstName} - {lastName} - {designation}");
        }
    }
}

Using connection = New SqliteConnection("Data Source=employee.db")
	Dim command = connection.CreateCommand()
	command.CommandText = "SELECT * FROM Employee"
	connection.Open()
	Using reader = command.ExecuteReader()
		Do While reader.Read()
			Dim id = reader.GetInt32(0)
			Dim firstName As String = reader.GetString(1)
			Dim lastName As String = reader.GetString(2).ToString()
			Dim designation As String = reader.GetString(3).ToString()
			Console.WriteLine($"{id}: {firstName} - {lastName} - {designation}")
		Loop
	End Using
End Using

Querying data

If you prefer to use LINQ to query your SQLite database, you can use Entity Framework Core to map your tables to classes and perform queries using LINQ expressions. To do this, you need to install the Microsoft.EntityFrameworkCore.Sqlite package, which depends on Microsoft.Data.Sqlite package. You also need to create a class that inherits from DbContext and represents the database context. This class must have a constructor that accepts a DbContextOptions parameter and passes it to the base constructor. It must also have a DbSet property for each table you want to map to a class. For example, the following code defines a Stock class and a DatabaseContext class:

using Microsoft.EntityFrameworkCore;
public class Stock
{
    public int Id { get; set; }
    public string Name { get; set; } = string.Empty;
    public string Symbol { get; set; } = string.Empty;
    public double Price { get; set; }
}
public class DatabaseContext : DbContext
{
    public DatabaseContext(DbContextOptions options) : base(options) { }
    public DbSet<Stock> Stock { get; set; }
}

using Microsoft.EntityFrameworkCore;
public class Stock
{
    public int Id { get; set; }
    public string Name { get; set; } = string.Empty;
    public string Symbol { get; set; } = string.Empty;
    public double Price { get; set; }
}
public class DatabaseContext : DbContext
{
    public DatabaseContext(DbContextOptions options) : base(options) { }
    public DbSet<Stock> Stock { get; set; }
}

Imports Microsoft.EntityFrameworkCore
Public Class Stock
	Public Property Id() As Integer
	Public Property Name() As String = String.Empty
	Public Property Symbol() As String = String.Empty
	Public Property Price() As Double
End Class
Public Class DatabaseContext
	Inherits DbContext

	Public Sub New(ByVal options As DbContextOptions)
		MyBase.New(options)
	End Sub
	Public Property Stock() As DbSet(Of Stock)
End Class

To create the database context, you need to use the DbContextOptionsBuilder class and specify the connection string and the database provider. You can also use the Database.EnsureCreated method to create the database and the tables if they do not exist. For example, the following code creates the database context and the database:

var optionsBuilder = new DbContextOptionsBuilder<DatabaseContext>();
  optionsBuilder.UseSqlite("Data Source=stock.db");
  using (var context = new DatabaseContext(optionsBuilder.Options))
  {
      context.Database.EnsureCreated();
  }

var optionsBuilder = new DbContextOptionsBuilder<DatabaseContext>();
  optionsBuilder.UseSqlite("Data Source=stock.db");
  using (var context = new DatabaseContext(optionsBuilder.Options))
  {
      context.Database.EnsureCreated();
  }

Dim optionsBuilder = New DbContextOptionsBuilder(Of DatabaseContext)()
  optionsBuilder.UseSqlite("Data Source=stock.db")
  Using context = New DatabaseContext(optionsBuilder.Options)
	  context.Database.EnsureCreated()
  End Using

To insert data into the database, you can use the Add or AddRange methods of the DbSet property and pass the objects you want to insert. You can also use the SaveChanges method to commit the changes to the database. For example, the following code inserts three Stocks into the database:

static void Main(string [] args)
{
    var optionsBuilder = new DbContextOptionsBuilder<DatabaseContext>();
    optionsBuilder.UseSqlite("Data Source=stock.db");
    using (var context = new DatabaseContext(optionsBuilder.Options))
    {
        context.Database.EnsureCreated();
        var stock = new List<Stock> {
        new Stock { Id = 1, Name = "NCR" , Symbol = "$$", Price = 5.6 },
        new Stock { Id = 2, Name = "Google" , Symbol = "GG", Price = 10.6 },
        new Stock { Id = 3, Name = "Apple" , Symbol = "AA", Price = 3.6 }
        };
        context.AddRange(stock);
        context.SaveChanges();
    }
}

static void Main(string [] args)
{
    var optionsBuilder = new DbContextOptionsBuilder<DatabaseContext>();
    optionsBuilder.UseSqlite("Data Source=stock.db");
    using (var context = new DatabaseContext(optionsBuilder.Options))
    {
        context.Database.EnsureCreated();
        var stock = new List<Stock> {
        new Stock { Id = 1, Name = "NCR" , Symbol = "$$", Price = 5.6 },
        new Stock { Id = 2, Name = "Google" , Symbol = "GG", Price = 10.6 },
        new Stock { Id = 3, Name = "Apple" , Symbol = "AA", Price = 3.6 }
        };
        context.AddRange(stock);
        context.SaveChanges();
    }
}

Shared Sub Main(ByVal args() As String)
	Dim optionsBuilder = New DbContextOptionsBuilder(Of DatabaseContext)()
	optionsBuilder.UseSqlite("Data Source=stock.db")
	Using context = New DatabaseContext(optionsBuilder.Options)
		context.Database.EnsureCreated()
		Dim stock As New List(Of Stock) From {
			New Stock With {
				.Id = 1,
				.Name = "NCR",
				.Symbol = "$$",
				.Price = 5.6
			},
			New Stock With {
				.Id = 2,
				.Name = "Google",
				.Symbol = "GG",
				.Price = 10.6
			},
			New Stock With {
				.Id = 3,
				.Name = "Apple",
				.Symbol = "AA",
				.Price = 3.6
			}
		}
		context.AddRange(stock)
		context.SaveChanges()
	End Using
End Sub

To query data, you can use the LINQ methods or expressions on the DbSet property and apply filters, projections, aggregations, and other operations. The queries will be translated to SQL statements and executed on the database. For example, the following code queries the stocks whose price is less than six dollars and prints their names:

using (var context = new DatabaseContext(optionsBuilder.Options))
{
    var cheapStocks = context.Stock.Where(p => p.Price < 6).Select(p => p.Name);
    Console.WriteLine("Stock Less than $6 are:");
    foreach (string stock in cheapStocks)
    {
        Console.WriteLine(stock);
    }
}

using (var context = new DatabaseContext(optionsBuilder.Options))
{
    var cheapStocks = context.Stock.Where(p => p.Price < 6).Select(p => p.Name);
    Console.WriteLine("Stock Less than $6 are:");
    foreach (string stock in cheapStocks)
    {
        Console.WriteLine(stock);
    }
}

Using context = New DatabaseContext(optionsBuilder.Options)
	Dim cheapStocks = context.Stock.Where(Function(p) p.Price < 6).Select(Function(p) p.Name)
	Console.WriteLine("Stock Less than $6 are:")
	For Each stock As String In cheapStocks
		Console.WriteLine(stock)
	Next stock
End Using

Let's suppose, we have a scenario, where we need to create a PDF file containing the list of Stocks. We can easily do that by using IronPDF.

Create PDF File from Containing Stock List

This C# code generates a PDF report from stock data stored in a SQLite database. It dynamically creates an HTML table, populates it with stock information, and uses a Chrome-based PDF renderer to convert the table into a downloadable "stock.pdf" file, facilitating efficient reporting and distribution of stock details.

The above C# code snippet is designed to create an HTML table displaying stock information from a SQLite database and subsequently convert it into a PDF file. It uses the Entity Framework Core library to interact with the database. Initially, it configures a DbContextOptionsBuilder to use SQLite with a specific connection string. The code then constructs an HTML string with embedded CSS styles for the table's appearance, creates a table structure with headers, queries the SQLite database for stock information, populates the HTML table with the retrieved data, and finally, utilizes a Chrome-based PDF renderer to convert the HTML content into a PDF file named "stock.pdf." The resulting PDF will contain a table presenting stock symbols, names, and prices.
