What is the purpose of the BatchUpdate method in ADO.NET?

The BatchUpdate method is used to send multiple SQL commands (such as insert, update,

or delete) in a single round trip to the database. This improves performance by reducing the

overhead of sending multiple individual commands.

While BatchUpdate isn't directly exposed as a method on the DataAdapter object, you

can achieve similar functionality by manually creating a batch of commands and executing

them in a single call.

Example (Using SqlDataAdapter):

SqlDataAdapter adapter = new SqlDataAdapter("SELECT * FROM

Customers", connection);

SqlCommandBuilder builder = new SqlCommandBuilder(adapter); //

Automatically generates commands for Update, Insert, and Delete

DataTable table = new DataTable();

adapter.Fill(table);

// Modify DataTable as needed

// Update changes to the database in one go (BatchUpdate)

adapter.Update(table);
