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

NetSuiteDataAdapter adapter = new NetSuiteDataAdapter();

using (NetSuiteConnection conn = new NetSuiteConnection("AccountId=XABC123456;Schema=SuiteTalk;AuthScheme=Token;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;OAuthAccessToken=MyOAuthAccessToken;OAuthAccessTokenSecret=MyOAuthAccessTokenSecret;")) {
  conn.Open();
  adapter.InsertCommand = conn.CreateCommand();
  adapter.InsertCommand.CommandText = "INSERT INTO Account (AcctName) VALUES (@AcctName)";
  adapter.InsertCommand.UpdatedRowSource = UpdateRowSource.None;
  adapter.InsertCommand.Parameters.Add("@AcctName", "AcctName");

  DataTable batchDataTable = new DataTable();
  batchDataTable.Columns.Add("AcctName", typeof(string));
  batchDataTable.Rows.Add("Savings");
  batchDataTable.Rows.Add("Petty Cash");
  adapter.UpdateBatchSize = 2;
  adapter.Update(batchDataTable);

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

Using conn As New NetSuiteConnection("AccountId=XABC123456;Schema=SuiteTalk;AuthScheme=Token;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;OAuthAccessToken=MyOAuthAccessToken;OAuthAccessTokenSecret=MyOAuthAccessTokenSecret;")
  conn.Open()
  adapter.InsertCommand = conn.CreateCommand()
  adapter.InsertCommand.CommandText = "INSERT INTO Account (InternalId) VALUES (@AcctName)"
  adapter.InsertCommand.UpdatedRowSource = UpdateRowSource.None
  adapter.InsertCommand.Parameters.Add("@AcctName", "AcctName")

  Dim batchDataTable As New DataTable()
  batchDataTable.Columns.Add("AcctName", GetType(String))
  batchDataTable.Rows.Add("Petty Cash")
  batchDataTable.Rows.Add("Savings")
  adapter.UpdateBatchSize = 2
  adapter.Update(batchDataTable)

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

NetSuiteDataAdapter adapter = new NetSuiteDataAdapter();

using (NetSuiteConnection conn = new NetSuiteConnection("AccountId=XABC123456;Schema=SuiteTalk;AuthScheme=Token;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;OAuthAccessToken=MyOAuthAccessToken;OAuthAccessTokenSecret=MyOAuthAccessTokenSecret;")) { 
  conn.Open();
  adapter.UpdateCommand = conn.CreateCommand();
  adapter.UpdateCommand.CommandText = "UPDATE Account SET AcctName=@AcctName WHERE InternalId=@InternalId";
  adapter.UpdateCommand.Parameters.Add("@AcctName", "AcctName");
  adapter.UpdateCommand.Parameters.Add("@InternalId", "InternalId");
  adapter.UpdateCommand.UpdatedRowSource = UpdateRowSource.None; 
  DataTable batchDataTable = new DataTable();
  batchDataTable.Columns.Add("AcctName", typeof(string));
  batchDataTable.Rows.Add("Savings");
  batchDataTable.Rows.Add("Petty Cash");
  adapter.UpdateBatchSize = 2;
  adapter.Update(dataTable);
}

VB.NET

 
Dim adapter As New NetSuiteDataAdapter()

Using conn As New NetSuiteConnection("AccountId=XABC123456;Schema=SuiteTalk;AuthScheme=Token;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;OAuthAccessToken=MyOAuthAccessToken;OAuthAccessTokenSecret=MyOAuthAccessTokenSecret;")
  conn.Open()
  adapter.UpdateCommand = conn.CreateCommand()
  adapter.UpdateCommand.CommandText = "UPDATE Account SET AcctName=@AcctName WHERE InternalId=@InternalId"
  adapter.UpdateCommand.Parameters.Add("@AcctName", "AcctName")
  adapter.UpdateCommand.Parameters.Add("@InternalId", "InternalId")
  adapter.UpdateCommand.UpdatedRowSource = UpdateRowSource.None
  Dim batchDataTable As New DataTable()
  batchDataTable.Columns.Add("AcctName", GetType(String))
  batchDataTable.Rows.Add("Petty Cash")
  batchDataTable.Rows.Add("Savings")
  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#

NetSuiteDataAdapter adapter = new NetSuiteDataAdapter();

using (NetSuiteConnection conn = new NetSuiteConnection("AccountId=XABC123456;Schema=SuiteTalk;AuthScheme=Token;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;OAuthAccessToken=MyOAuthAccessToken;OAuthAccessTokenSecret=MyOAuthAccessTokenSecret;")) {
  conn.Open();
  adapter.DeleteCommand = conn.CreateCommand();
  adapter.DeleteCommand.CommandText = "DELETE FROM Account WHERE InternalId=@InternalId";
  adapter.DeleteCommand.Parameters.Add("@InternalId", "InternalId");
  adapter.DeleteCommand.UpdatedRowSource = UpdateRowSource.None; 
  adapter.UpdateBatchSize = 2;
  adpater.Update(table);
}

VB.NET

Dim adapter As New NetSuiteDataAdapter()

Using conn As New NetSuiteConnection("AccountId=XABC123456;Schema=SuiteTalk;AuthScheme=Token;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;OAuthAccessToken=MyOAuthAccessToken;OAuthAccessTokenSecret=MyOAuthAccessTokenSecret;")
  conn.Open()
  adapter.DeleteCommand = conn.CreateCommand()
  adapter.DeleteCommand.CommandText = "DELETE FROM Account WHERE InternalId=@InternalId"
  adapter.DeleteCommand.Parameters.Add("@InternalId", "InternalId")
  adapter.DeleteCommand.UpdatedRowSource = UpdateRowSource.None 
  adapter.UpdateBatchSize = 2
  adpater.Update(table)
End Using
