connection.BulkInsert(customers);

public class Customer {
    public int Id { get; set; }

}

using ETLBox.DbExtensions;

var connection = new SqlConnection("your-connection-string");
var customers = Enumerable.Range(1, 10_000)
    .Select(i => new Customer { Id = i, Name = $"Customer {i}", City = "Merged City" });
connection.BulkMerge(customers, options => {
    options.MergeMode = MergeMode.Full;
});

public class Customer : MergeableRow {
    [IdColumn]
    public int Id { get; set; }
    public string Name { get; set; }
    public string City { get; set; }
}

using ETLBox.DbExtensions;

var connection = new SqlConnection("your-connection-string");
var customers = Enumerable.Range(1, 10_000)
    .Select(i => new Customer { Id = i, Name = $"Updated {i}" });
connection.BulkUpdate(customers);

public class Customer {
    [IdColumn]
    public int Id { get; set; }
    public string Name { get; set; }
    public string City { get; set; }
}

using ETLBox.DbExtensions;

var connection = new SqlConnection("your-connection-string");
var customers = Enumerable.Range(1, 10_000)
    .Select(i => new Customer { Id = i });
connection.BulkDelete(customers);

public class Customer {
    [IdColumn]
    public int Id { get; set; }
    public string Name { get; set; }
    public string City { get; set; }
