NuGet NuGet Downloads

Description

Microsoft.Data.SqlClient is the official .NET data provider for Microsoft SQL Server and Azure SQL databases. It provides access to SQL Server and encapsulates database-specific protocols, including Tabular Data Stream (TDS).

This library grew from a union of the two System.Data.SqlClient components which live independently in .NET and .NET Framework. Going forward, support for new SQL Server and Azure SQL features will only be implemented in Microsoft.Data.SqlClient.

Supportability

This package supports:

  • .NET Framework 4.6.2+
  • .NET 8.0+

Installation

Install the package via NuGet:

dotnet add package Microsoft.Data.SqlClient

Or via the Package Manager Console:

Install-Package Microsoft.Data.SqlClient

Getting Started

Basic Connection

using Microsoft.Data.SqlClient;

var connectionString = "Server=myserver;Database=mydb;Integrated Security=true;";

using var connection = new SqlConnection(connectionString);
await connection.OpenAsync();

Console.WriteLine("Connected successfully!");

Execute a Query

using Microsoft.Data.SqlClient;

var connectionString = "Server=myserver;Database=mydb;Integrated Security=true;";

using var connection = new SqlConnection(connectionString);
await connection.OpenAsync();

using var command = new SqlCommand("SELECT Id, Name FROM Customers", connection);
using var reader = await command.ExecuteReaderAsync();

while (await reader.ReadAsync())
{
    Console.WriteLine($"Id: {reader.GetInt32(0)}, Name: {reader.GetString(1)}");
}

Parameterized Query

using Microsoft.Data.SqlClient;

var connectionString = "Server=myserver;Database=mydb;Integrated Security=true;";

using var connection = new SqlConnection(connectionString);
await connection.OpenAsync();

using var command = new SqlCommand("SELECT * FROM Customers WHERE Id = @id", connection);
command.Parameters.AddWithValue("@id", customerId);

using var reader = await command.ExecuteReaderAsync();
// Process results...

Using Transactions

using Microsoft.Data.SqlClient;

using var connection = new SqlConnection(connectionString);
await connection.OpenAsync();

using var transaction = connection.BeginTransaction();

try
{
    using var command = new SqlCommand("INSERT INTO Orders (CustomerId, Total) VALUES (@customerId, @total)", connection, transaction);
    command.Parameters.AddWithValue("@customerId", customerId);
    command.Parameters.AddWithValue("@total", orderTotal);
    
    await command.ExecuteNonQueryAsync();
    await transaction.CommitAsync();
}
catch
{
    await transaction.RollbackAsync();
    throw;
}
