  • Open: MIT license; development happens on GitHub with publicly visible roadmaps, issues, and PRs

About

MySqlConnector is an ADO.NET data provider for MySQL Server, MariaDB, Percona Server, Amazon Aurora, Azure Database for MySQL, Google Cloud SQL for MySQL and more. It provides implementations of DbConnection, DbCommand, DbDataReader, DbTransaction — the classes needed to query and update databases from managed code.

Getting Started

Install MySqlConnector from NuGet: dotnet add package MySqlConnector

Connecting to your database is simple. For example, in C#:

using (var connection = new MySqlConnection("Server=myserver;User ID=mylogin;Password=mypass;Database=mydatabase"))
{
    connection.Open();

    using (var command = new MySqlCommand("SELECT field FROM table;", connection))
    using (var reader = command.ExecuteReader())
        while (reader.Read())
            Console.WriteLine(reader.GetString(0));
}

For more information, see how to install and a basic example of using the API. Many ORMs are supported.

Why use MySqlConnector over Oracle’s Connector/NET?

MySqlConnector is a clean-room reimplementation of the MySQL Protocol and is not based on Oracle’s Connector/NET.
