The CData ADO.NET Provider for Microsoft Dynamics 365 Business Central enables you to take advantage of the bulk load support in Microsoft Dynamics 365 Business Central through D365BusinessCentralDataAdapters. 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 D365BusinessCentralCommand objects.
2. Set the UpdatedRowSource property of the D365BusinessCentralCommand object to "UpdateRowSource.None".
3. Assign the D365BusinessCentralCommand objects to the D365BusinessCentralDataAdapter.
4. Add the parameters to the command.
5. Call the D365BusinessCentralDataAdapter'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 D365BusinessCentralDataAdapter'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#

D365BusinessCentralDataAdapter adapter = new D365BusinessCentralDataAdapter();

using (D365BusinessCentralConnection conn = new D365BusinessCentralConnection("InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://api.businesscentral.dynamics.com/v1.0/api/v1.0")) {
  conn.Open();
  adapter.InsertCommand = conn.CreateCommand();
  adapter.InsertCommand.CommandText = "INSERT INTO Accounts (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("Jon Doe");
  batchDataTable.Rows.Add("John");
  adapter.UpdateBatchSize = 2;
  adapter.Update(batchDataTable);

  D365BusinessCentralCommand cmd = new D365BusinessCentralCommand("SELECT * FROM LastResultInfo#TEMP", conn);
  adapter = new D365BusinessCentralDataAdapter(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 D365BusinessCentralDataAdapter()

Using conn As New D365BusinessCentralConnection("InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://api.businesscentral.dynamics.com/v1.0/api/v1.0")
  conn.Open()
  adapter.InsertCommand = conn.CreateCommand()
  adapter.InsertCommand.CommandText = "INSERT INTO Accounts (accountid) 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("John")
  batchDataTable.Rows.Add("Jon Doe")
  adapter.UpdateBatchSize = 2
  adapter.Update(batchDataTable)

  Dim cmd As New D365BusinessCentralCommand("SELECT * FROM LastResultInfo#TEMP", conn)
  adapter = New D365BusinessCentralDataAdapter(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#

D365BusinessCentralDataAdapter adapter = new D365BusinessCentralDataAdapter();

using (D365BusinessCentralConnection conn = new D365BusinessCentralConnection("InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://api.businesscentral.dynamics.com/v1.0/api/v1.0")) { 
  conn.Open();
  adapter.UpdateCommand = conn.CreateCommand();
  adapter.UpdateCommand.CommandText = "UPDATE Accounts SET Name=@Name WHERE AccountId=@AccountId";
  adapter.UpdateCommand.Parameters.Add("@Name", "Name");
  adapter.UpdateCommand.Parameters.Add("@AccountId", "AccountId");
  adapter.UpdateCommand.UpdatedRowSource = UpdateRowSource.None; 
  adapter.UpdateBatchSize = 2;
  adapter.Update(dataTable);
}

VB.NET

 
Dim adapter As New D365BusinessCentralDataAdapter()

Using conn As New D365BusinessCentralConnection("InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://api.businesscentral.dynamics.com/v1.0/api/v1.0")
  conn.Open()
  adapter.UpdateCommand = conn.CreateCommand()
  adapter.UpdateCommand.CommandText = "UPDATE Accounts SET Name=@Name WHERE AccountId=@AccountId"
  adapter.UpdateCommand.Parameters.Add("@Name", "Name")
  adapter.UpdateCommand.Parameters.Add("@AccountId", "AccountId")
  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#

D365BusinessCentralDataAdapter adapter = new D365BusinessCentralDataAdapter();

using (D365BusinessCentralConnection conn = new D365BusinessCentralConnection("InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://api.businesscentral.dynamics.com/v1.0/api/v1.0")) {
  conn.Open();
  adapter.DeleteCommand = conn.CreateCommand();
  adapter.DeleteCommand.CommandText = "DELETE FROM Accounts WHERE AccountId=@AccountId";
  adapter.DeleteCommand.Parameters.Add("@AccountId", "AccountId");
  adapter.DeleteCommand.UpdatedRowSource = UpdateRowSource.None; 
  adapter.UpdateBatchSize = 2;
  adpater.Update(table);
}

VB.NET

Dim adapter As New D365BusinessCentralDataAdapter()

Using conn As New D365BusinessCentralConnection("InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://api.businesscentral.dynamics.com/v1.0/api/v1.0")
  conn.Open()
  adapter.DeleteCommand = conn.CreateCommand()
  adapter.DeleteCommand.CommandText = "DELETE FROM Accounts WHERE AccountId=@AccountId"
  adapter.DeleteCommand.Parameters.Add("@AccountId", "AccountId")
  adapter.DeleteCommand.UpdatedRowSource = UpdateRowSource.None 
  adapter.UpdateBatchSize = 2
  adpater.Update(table)
End Using
