The CData ADO.NET Provider for Microsoft Dynamics 365 enables you to take advantage of the bulk load support in Microsoft Dynamics 365 through Dynamics365DataAdapters. 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 Dynamics365Command objects.
2. Set the UpdatedRowSource property of the Dynamics365Command object to "UpdateRowSource.None".
3. Assign the Dynamics365Command objects to the Dynamics365DataAdapter.
4. Add the parameters to the command.
5. Call the Dynamics365DataAdapter'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 Dynamics365DataAdapter'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#

Dynamics365DataAdapter adapter = new Dynamics365DataAdapter();

using (Dynamics365Connection conn = new Dynamics365Connection("InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://myaccount.operations.dynamics.com/;Edition=Sales;")) {
  conn.Open();
  adapter.InsertCommand = conn.CreateCommand();
  adapter.InsertCommand.CommandText = "INSERT INTO GoalHeadings (GoalHeadingId) VALUES (@GoalHeadingId)";
  adapter.InsertCommand.UpdatedRowSource = UpdateRowSource.None;
  adapter.InsertCommand.Parameters.Add("@GoalHeadingId", "GoalHeadingId");

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

  Dynamics365Command cmd = new Dynamics365Command("SELECT * FROM LastResultInfo#TEMP", conn);
  adapter = new Dynamics365DataAdapter(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 Dynamics365DataAdapter()

Using conn As New Dynamics365Connection("InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://myaccount.operations.dynamics.com/;Edition=Sales;")
  conn.Open()
  adapter.InsertCommand = conn.CreateCommand()
  adapter.InsertCommand.CommandText = "INSERT INTO GoalHeadings (GoalHeadingId) VALUES (@GoalHeadingId)"
  adapter.InsertCommand.UpdatedRowSource = UpdateRowSource.None
  adapter.InsertCommand.Parameters.Add("@GoalHeadingId", "GoalHeadingId")

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

  Dim cmd As New Dynamics365Command("SELECT * FROM LastResultInfo#TEMP", conn)
  adapter = New Dynamics365DataAdapter(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#

Dynamics365DataAdapter adapter = new Dynamics365DataAdapter();

using (Dynamics365Connection conn = new Dynamics365Connection("InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://myaccount.operations.dynamics.com/;Edition=Sales;")) { 
  conn.Open();
  adapter.UpdateCommand = conn.CreateCommand();
  adapter.UpdateCommand.CommandText = "UPDATE GoalHeadings SET GoalHeadingId=@GoalHeadingId WHERE GoalHeadingId=@GoalHeadingId";
  adapter.UpdateCommand.Parameters.Add("@GoalHeadingId", "GoalHeadingId");
  adapter.UpdateCommand.Parameters.Add("@GoalHeadingId", "GoalHeadingId");
  adapter.UpdateCommand.UpdatedRowSource = UpdateRowSource.None; 
  adapter.UpdateBatchSize = 2;
  adapter.Update(dataTable);
}

VB.NET

 
Dim adapter As New Dynamics365DataAdapter()

Using conn As New Dynamics365Connection("InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://myaccount.operations.dynamics.com/;Edition=Sales;")
  conn.Open()
  adapter.UpdateCommand = conn.CreateCommand()
  adapter.UpdateCommand.CommandText = "UPDATE GoalHeadings SET GoalHeadingId=@GoalHeadingId WHERE GoalHeadingId=@GoalHeadingId"
  adapter.UpdateCommand.Parameters.Add("@GoalHeadingId", "GoalHeadingId")
  adapter.UpdateCommand.Parameters.Add("@GoalHeadingId", "GoalHeadingId")
  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#

Dynamics365DataAdapter adapter = new Dynamics365DataAdapter();

using (Dynamics365Connection conn = new Dynamics365Connection("InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://myaccount.operations.dynamics.com/;Edition=Sales;")) {
  conn.Open();
  adapter.DeleteCommand = conn.CreateCommand();
  adapter.DeleteCommand.CommandText = "DELETE FROM GoalHeadings WHERE GoalHeadingId=@GoalHeadingId";
  adapter.DeleteCommand.Parameters.Add("@GoalHeadingId", "GoalHeadingId");
  adapter.DeleteCommand.UpdatedRowSource = UpdateRowSource.None; 
  adapter.UpdateBatchSize = 2;
  adpater.Update(table);
}

VB.NET

Dim adapter As New Dynamics365DataAdapter()

Using conn As New Dynamics365Connection("InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://myaccount.operations.dynamics.com/;Edition=Sales;")
  conn.Open()
  adapter.DeleteCommand = conn.CreateCommand()
  adapter.DeleteCommand.CommandText = "DELETE FROM GoalHeadings WHERE GoalHeadingId=@GoalHeadingId"
  adapter.DeleteCommand.Parameters.Add("@GoalHeadingId", "GoalHeadingId")
  adapter.DeleteCommand.UpdatedRowSource = UpdateRowSource.None 
  adapter.UpdateBatchSize = 2
  adpater.Update(table)
End Using
