The CData ADO.NET Provider for WooCommerce enables you to take advantage of the bulk load support in WooCommerce through WooCommerceDataAdapters. You can use the Batch API to execute related SQL data manipulation statements simultaneously. The provider translates all SQL queries in the batch into a single request.

Using the ADO.NET Batch API

Performing a batch update consists of the following basic steps:

1. Define custom parameterized SQL statements in WooCommerceCommand objects.
2. Set the UpdatedRowSource property of the WooCommerceCommand object to "UpdateRowSource.None".
3. Assign the WooCommerceCommand objects to the WooCommerceDataAdapter.
4. Add the parameters to the command.
5. Call the WooCommerceDataAdapter's Update method. Pass in a DataSet or DataTable containing your changes.

Controlling Batch Size

Depending on factors such as the size of the request, your network resources, and the performance of the server, you may gain performance by executing several smaller batch requests. You can control the size of each batch by setting the WooCommerceDataAdapter's UpdateBatchSize property to a positive integer.

Bulk INSERT

The following code prepares a single batch that inserts records in bulk. The example executes a batch INSERT of new DataRows, which have the "Added" state.

C#

WooCommerceDataAdapter adapter = new WooCommerceDataAdapter();

using (WooCommerceConnection conn = new WooCommerceConnection(" Url=http://localhost/woocommerce/;ConsumerKey=ck_ec52c76185c088ecaa3145287c8acba55a6f59ad;ConsumerSecret=cs_9fde14bf57126156701a7563fc87575713c355e5;")) {
  conn.Open();
  adapter.InsertCommand = conn.CreateCommand();
  adapter.InsertCommand.CommandText = "INSERT INTO Orders (Total) VALUES (@Total)";
  adapter.InsertCommand.UpdatedRowSource = UpdateRowSource.None;
  adapter.InsertCommand.Parameters.Add("@Total", "Total");

  DataTable batchDataTable = new DataTable();
  batchDataTable.Columns.Add("Total", typeof(string));
  batchDataTable.Rows.Add("Jon Doe");
  batchDataTable.Rows.Add("John");
  adapter.UpdateBatchSize = 2;
  adapter.Update(batchDataTable);
}

VB.NET

 
Dim adapter As New WooCommerceDataAdapter()

Using conn As New WooCommerceConnection(" Url=http://localhost/woocommerce/;ConsumerKey=ck_ec52c76185c088ecaa3145287c8acba55a6f59ad;ConsumerSecret=cs_9fde14bf57126156701a7563fc87575713c355e5;")
  conn.Open()
  adapter.InsertCommand = conn.CreateCommand()
  adapter.InsertCommand.CommandText = "INSERT INTO Orders (ParentId) VALUES (@Total)"
  adapter.InsertCommand.UpdatedRowSource = UpdateRowSource.None
  adapter.InsertCommand.Parameters.Add("@Total", "Total")

  Dim batchDataTable As New DataTable()
  batchDataTable.Columns.Add("Total", GetType(String))
  batchDataTable.Rows.Add("John")
  batchDataTable.Rows.Add("Jon Doe")
  adapter.UpdateBatchSize = 2
  adapter.Update(batchDataTable)
End Using

Bulk Update

A batch update additionally requires the primary key of each row to update. The following example executes a batch for all DataRow records with a "Modified" state:

C#

WooCommerceDataAdapter adapter = new WooCommerceDataAdapter();

using (WooCommerceConnection conn = new WooCommerceConnection(" Url=http://localhost/woocommerce/;ConsumerKey=ck_ec52c76185c088ecaa3145287c8acba55a6f59ad;ConsumerSecret=cs_9fde14bf57126156701a7563fc87575713c355e5;")) { 
  conn.Open();
  adapter.UpdateCommand = conn.CreateCommand();
  adapter.UpdateCommand.CommandText = "UPDATE Orders SET Total=@Total WHERE Id=@Id";
  adapter.UpdateCommand.Parameters.Add("@Total", "Total");
  adapter.UpdateCommand.Parameters.Add("@Id", "Id");
  adapter.UpdateCommand.UpdatedRowSource = UpdateRowSource.None; 
  adapter.UpdateBatchSize = 2;
  adapter.Update(dataTable);
}

VB.NET

 
Dim adapter As New WooCommerceDataAdapter()

Using conn As New WooCommerceConnection(" Url=http://localhost/woocommerce/;ConsumerKey=ck_ec52c76185c088ecaa3145287c8acba55a6f59ad;ConsumerSecret=cs_9fde14bf57126156701a7563fc87575713c355e5;")
  conn.Open()
  adapter.UpdateCommand = conn.CreateCommand()
  adapter.UpdateCommand.CommandText = "UPDATE Orders SET Total=@Total WHERE Id=@Id"
  adapter.UpdateCommand.Parameters.Add("@Total", "Total")
  adapter.UpdateCommand.Parameters.Add("@Id", "Id")
  adapter.UpdateCommand.UpdatedRowSource = UpdateRowSource.None
  adapter.UpdateBatchSize = 2
  adapter.Update(dataTable)
End Using

Bulk Delete

The following code prepares a single batch that deletes records in bulk. The primary key for each row is required. The following example executes a batch for all DataRow records with a "Deleted" state:

C#

WooCommerceDataAdapter adapter = new WooCommerceDataAdapter();

using (WooCommerceConnection conn = new WooCommerceConnection(" Url=http://localhost/woocommerce/;ConsumerKey=ck_ec52c76185c088ecaa3145287c8acba55a6f59ad;ConsumerSecret=cs_9fde14bf57126156701a7563fc87575713c355e5;")) {
  conn.Open();
  adapter.DeleteCommand = conn.CreateCommand();
  adapter.DeleteCommand.CommandText = "DELETE FROM Orders WHERE Id=@Id";
  adapter.DeleteCommand.Parameters.Add("@Id", "Id");
  adapter.DeleteCommand.UpdatedRowSource = UpdateRowSource.None; 
  adapter.UpdateBatchSize = 2;
  adpater.Update(table);
}

VB.NET

Dim adapter As New WooCommerceDataAdapter()

Using conn As New WooCommerceConnection(" Url=http://localhost/woocommerce/;ConsumerKey=ck_ec52c76185c088ecaa3145287c8acba55a6f59ad;ConsumerSecret=cs_9fde14bf57126156701a7563fc87575713c355e5;")
  conn.Open()
  adapter.DeleteCommand = conn.CreateCommand()
  adapter.DeleteCommand.CommandText = "DELETE FROM Orders WHERE Id=@Id"
  adapter.DeleteCommand.Parameters.Add("@Id", "Id")
  adapter.DeleteCommand.UpdatedRowSource = UpdateRowSource.None 
  adapter.UpdateBatchSize = 2
  adpater.Update(table)
End Using
