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

OdooDataAdapter adapter = new OdooDataAdapter();

using (OdooConnection conn = new OdooConnection("User=MyUser;APIToken=MyToken;URL=https://MyOdooSite;Database=MyDatabase")) {
  conn.Open();
  adapter.InsertCommand = conn.CreateCommand();
  adapter.InsertCommand.CommandText = "INSERT INTO res_users (email) VALUES (@email)";
  adapter.InsertCommand.UpdatedRowSource = UpdateRowSource.None;
  adapter.InsertCommand.Parameters.Add("@email", "email");

  DataTable batchDataTable = new DataTable();
  batchDataTable.Columns.Add("email", typeof(string));
  batchDataTable.Rows.Add("[email protected]");
  batchDataTable.Rows.Add("John");
  adapter.UpdateBatchSize = 2;
  adapter.Update(batchDataTable);

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

Using conn As New OdooConnection("User=MyUser;APIToken=MyToken;URL=https://MyOdooSite;Database=MyDatabase")
  conn.Open()
  adapter.InsertCommand = conn.CreateCommand()
  adapter.InsertCommand.CommandText = "INSERT INTO res_users (name) VALUES (@email)"
  adapter.InsertCommand.UpdatedRowSource = UpdateRowSource.None
  adapter.InsertCommand.Parameters.Add("@email", "email")

  Dim batchDataTable As New DataTable()
  batchDataTable.Columns.Add("email", GetType(String))
  batchDataTable.Rows.Add("John")
  batchDataTable.Rows.Add("[email protected]")
  adapter.UpdateBatchSize = 2
  adapter.Update(batchDataTable)

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

OdooDataAdapter adapter = new OdooDataAdapter();

using (OdooConnection conn = new OdooConnection("User=MyUser;APIToken=MyToken;URL=https://MyOdooSite;Database=MyDatabase")) {
  conn.Open();
  adapter.DeleteCommand = conn.CreateCommand();
  adapter.DeleteCommand.CommandText = "DELETE FROM res_users 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 OdooDataAdapter()

Using conn As New OdooConnection("User=MyUser;APIToken=MyToken;URL=https://MyOdooSite;Database=MyDatabase")
  conn.Open()
  adapter.DeleteCommand = conn.CreateCommand()
  adapter.DeleteCommand.CommandText = "DELETE FROM res_users WHERE id=@id"
  adapter.DeleteCommand.Parameters.Add("@id", "id")
  adapter.DeleteCommand.UpdatedRowSource = UpdateRowSource.None 
  adapter.UpdateBatchSize = 2
  adpater.Update(table)
End Using
