The CData ADO.NET Provider for Twitter Ads enables you to take advantage of the bulk load support in Twitter Ads through TwitterAdsDataAdapters. 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 TwitterAdsCommand objects.
2. Set the UpdatedRowSource property of the TwitterAdsCommand object to "UpdateRowSource.None".
3. Assign the TwitterAdsCommand objects to the TwitterAdsDataAdapter.
4. Add the parameters to the command.
5. Call the TwitterAdsDataAdapter'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 TwitterAdsDataAdapter's UpdateBatchSize property to a positive integer.

Bulk INSERT

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

C#

TwitterAdsDataAdapter adapter = new TwitterAdsDataAdapter();

using (TwitterAdsConnection conn = new TwitterAdsConnection("InitiateOAuth=GETANDREFRESH;")) {
  conn.Open();
  adapter.InsertCommand = conn.CreateCommand();
  adapter.InsertCommand.CommandText = "INSERT INTO AdAudiences (Name) VALUES (@Name)";
  adapter.InsertCommand.UpdatedRowSource = UpdateRowSource.None;
  adapter.InsertCommand.Parameters.Add("@Name", "Name");

  DataTable batchDataTable = new DataTable();
  batchDataTable.Columns.Add("Name", typeof(string));
  batchDataTable.Rows.Add("ORGANIC_TWEET");
  batchDataTable.Rows.Add("ORGANIC_TWEET");
  adapter.UpdateBatchSize = 2;
  adapter.Update(batchDataTable);

  TwitterAdsCommand cmd = new TwitterAdsCommand("SELECT * FROM LastResultInfo#TEMP", conn);
  adapter = new TwitterAdsDataAdapter(cmd);
  DataTable res = new DataTable();
  adapter.Fill(res);
  foreach (DataRow row in res.Rows) 
    foreach(DataColumn col in res.Columns)
      Console.Write("{0}: {1}", col.ColumnName, row[col]);
}

VB.NET

 
Dim adapter As New TwitterAdsDataAdapter()

Using conn As New TwitterAdsConnection("InitiateOAuth=GETANDREFRESH;")
  conn.Open()
  adapter.InsertCommand = conn.CreateCommand()
  adapter.InsertCommand.CommandText = "INSERT INTO AdAudiences (Id) VALUES (@Name)"
  adapter.InsertCommand.UpdatedRowSource = UpdateRowSource.None
  adapter.InsertCommand.Parameters.Add("@Name", "Name")

  Dim batchDataTable As New DataTable()
  batchDataTable.Columns.Add("Name", GetType(String))
  batchDataTable.Rows.Add("ORGANIC_TWEET")
  batchDataTable.Rows.Add("ORGANIC_TWEET")
  adapter.UpdateBatchSize = 2
  adapter.Update(batchDataTable)

  Dim cmd As New TwitterAdsCommand("SELECT * FROM LastResultInfo#TEMP", conn)
  adapter = New TwitterAdsDataAdapter(cmd)
  Dim res As New DataTable()
  adapter.Fill(res)
  For Each row As DataRow In res.Rows 
    For Each col As DataColumn In res.Columns
      Console.WriteLine("{0}: {1}", col.ColumnName, row(col))
    Next
  Next
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#

TwitterAdsDataAdapter adapter = new TwitterAdsDataAdapter();

using (TwitterAdsConnection conn = new TwitterAdsConnection("InitiateOAuth=GETANDREFRESH;")) { 
  conn.Open();
  adapter.UpdateCommand = conn.CreateCommand();
  adapter.UpdateCommand.CommandText = "UPDATE AdAudiences SET Name=@Name WHERE Id=@Id";
  adapter.UpdateCommand.Parameters.Add("@Name", "Name");
  adapter.UpdateCommand.Parameters.Add("@Id", "Id");
  adapter.UpdateCommand.UpdatedRowSource = UpdateRowSource.None; 
  DataTable batchDataTable = new DataTable();
  batchDataTable.Columns.Add("Name", typeof(string));
  batchDataTable.Rows.Add("ORGANIC_TWEET");
  batchDataTable.Rows.Add("ORGANIC_TWEET");
  adapter.UpdateBatchSize = 2;
  adapter.Update(dataTable);
}

VB.NET

 
Dim adapter As New TwitterAdsDataAdapter()

Using conn As New TwitterAdsConnection("InitiateOAuth=GETANDREFRESH;")
  conn.Open()
  adapter.UpdateCommand = conn.CreateCommand()
  adapter.UpdateCommand.CommandText = "UPDATE AdAudiences SET Name=@Name WHERE Id=@Id"
  adapter.UpdateCommand.Parameters.Add("@Name", "Name")
  adapter.UpdateCommand.Parameters.Add("@Id", "Id")
  adapter.UpdateCommand.UpdatedRowSource = UpdateRowSource.None
  Dim batchDataTable As New DataTable()
  batchDataTable.Columns.Add("Name", GetType(String))
  batchDataTable.Rows.Add("ORGANIC_TWEET")
  batchDataTable.Rows.Add("ORGANIC_TWEET")
  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#

TwitterAdsDataAdapter adapter = new TwitterAdsDataAdapter();

using (TwitterAdsConnection conn = new TwitterAdsConnection("InitiateOAuth=GETANDREFRESH;")) {
  conn.Open();
  adapter.DeleteCommand = conn.CreateCommand();
  adapter.DeleteCommand.CommandText = "DELETE FROM AdAudiences 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 TwitterAdsDataAdapter()

Using conn As New TwitterAdsConnection("InitiateOAuth=GETANDREFRESH;")
  conn.Open()
  adapter.DeleteCommand = conn.CreateCommand()
  adapter.DeleteCommand.CommandText = "DELETE FROM AdAudiences WHERE Id=@Id"
  adapter.DeleteCommand.Parameters.Add("@Id", "Id")
  adapter.DeleteCommand.UpdatedRowSource = UpdateRowSource.None 
  adapter.UpdateBatchSize = 2
  adpater.Update(table)
End Using
