Inserting data into the database is one of the CRUD operations that act on an individual row by inserting a row.

The Dapper.SimpleCRUD library provides Insert extension method to insert data into the database.

The following example inserts a single new record.

private static void InsertSingleAuthor()
{
    using (IDbConnection db = new SqlConnection(ConnectionString))
    {
        Author author = new Author()
        {
            FirstName = "Cokie",
            LastName = "Roberts"
        };

        db.Insert<Author>(author);
    }
}

If you retrieve all the authors from the database, you will see that the above record is inserted at the end.

private static List<Author> GetAllAuthors()
{
    using (IDbConnection db = new SqlConnection(ConnectionString))
    {
        List<Author> authors = db.GetList<Author>().ToList();
        return authors;
    }
}

The following code calls the InsertSingleAuthor method and then retrieves all the authors from the database and prints them on the console.

static void Main(string[] args)
{
    InsertSingleAuthor();
    List<Author> authors = GetAllAuthors();

    foreach (var author in authors)
    {
        Console.WriteLine(author.FirstName + " " + author.LastName);
    }
}

Let's execute the above code, and if you retrieve all the authors and books from the database, you will see that the new records are added at the end.
