The CData ADO.NET Provider for Asana enables you to take advantage of the bulk load support in Asana through AsanaDataAdapters. 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 AsanaCommand objects.
2. Set the UpdatedRowSource property of the AsanaCommand object to "UpdateRowSource.None".
3. Assign the AsanaCommand objects to the AsanaDataAdapter.
4. Add the parameters to the command.
5. Call the AsanaDataAdapter'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 AsanaDataAdapter'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#

AsanaDataAdapter adapter = new AsanaDataAdapter();

using (AsanaConnection conn = new AsanaConnection("InitiateOAuth=GETANDREFRESH;OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CallbackURL='http://localhost:33333'")) {
  conn.Open();
  adapter.InsertCommand = conn.CreateCommand();
  adapter.InsertCommand.CommandText = "INSERT INTO projects (WorkspaceId) VALUES (@WorkspaceId)";
  adapter.InsertCommand.UpdatedRowSource = UpdateRowSource.None;
  adapter.InsertCommand.Parameters.Add("@WorkspaceId", "WorkspaceId");

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

VB.NET

 
Dim adapter As New AsanaDataAdapter()

Using conn As New AsanaConnection("InitiateOAuth=GETANDREFRESH;OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CallbackURL='http://localhost:33333'")
  conn.Open()
  adapter.InsertCommand = conn.CreateCommand()
  adapter.InsertCommand.CommandText = "INSERT INTO projects (Id) VALUES (@WorkspaceId)"
  adapter.InsertCommand.UpdatedRowSource = UpdateRowSource.None
  adapter.InsertCommand.Parameters.Add("@WorkspaceId", "WorkspaceId")

  Dim batchDataTable As New DataTable()
  batchDataTable.Columns.Add("WorkspaceId", 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#

AsanaDataAdapter adapter = new AsanaDataAdapter();

using (AsanaConnection conn = new AsanaConnection("InitiateOAuth=GETANDREFRESH;OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CallbackURL='http://localhost:33333'")) { 
  conn.Open();
  adapter.UpdateCommand = conn.CreateCommand();
  adapter.UpdateCommand.CommandText = "UPDATE projects SET WorkspaceId=@WorkspaceId WHERE Id=@Id";
  adapter.UpdateCommand.Parameters.Add("@WorkspaceId", "WorkspaceId");
  adapter.UpdateCommand.Parameters.Add("@Id", "Id");
  adapter.UpdateCommand.UpdatedRowSource = UpdateRowSource.None; 
  DataTable batchDataTable = new DataTable();
  batchDataTable.Columns.Add("WorkspaceId", typeof(string));
  batchDataTable.Rows.Add("Jon Doe");
  batchDataTable.Rows.Add("John");
  adapter.UpdateBatchSize = 2;
  adapter.Update(dataTable);
}

VB.NET

 
Dim adapter As New AsanaDataAdapter()

Using conn As New AsanaConnection("InitiateOAuth=GETANDREFRESH;OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CallbackURL='http://localhost:33333'")
  conn.Open()
  adapter.UpdateCommand = conn.CreateCommand()
  adapter.UpdateCommand.CommandText = "UPDATE projects SET WorkspaceId=@WorkspaceId WHERE Id=@Id"
  adapter.UpdateCommand.Parameters.Add("@WorkspaceId", "WorkspaceId")
  adapter.UpdateCommand.Parameters.Add("@Id", "Id")
  adapter.UpdateCommand.UpdatedRowSource = UpdateRowSource.None
  Dim batchDataTable As New DataTable()
  batchDataTable.Columns.Add("WorkspaceId", GetType(String))
  batchDataTable.Rows.Add("John")
  batchDataTable.Rows.Add("Jon Doe")
  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#

AsanaDataAdapter adapter = new AsanaDataAdapter();

using (AsanaConnection conn = new AsanaConnection("InitiateOAuth=GETANDREFRESH;OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CallbackURL='http://localhost:33333'")) {
  conn.Open();
  adapter.DeleteCommand = conn.CreateCommand();
  adapter.DeleteCommand.CommandText = "DELETE FROM projects 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 AsanaDataAdapter()

Using conn As New AsanaConnection("InitiateOAuth=GETANDREFRESH;OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CallbackURL='http://localhost:33333'")
  conn.Open()
  adapter.DeleteCommand = conn.CreateCommand()
  adapter.DeleteCommand.CommandText = "DELETE FROM projects WHERE Id=@Id"
  adapter.DeleteCommand.Parameters.Add("@Id", "Id")
  adapter.DeleteCommand.UpdatedRowSource = UpdateRowSource.None 
  adapter.UpdateBatchSize = 2
  adpater.Update(table)
End Using
