Batch Processing
The CData ADO.NET Provider for Salesloft enables you to take advantage of the bulk load support in Salesloft through SalesLoftDataAdapters. 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:
- Define custom parameterized SQL statements in SalesLoftCommand objects.
- Set the UpdatedRowSource property of the SalesLoftCommand object to "UpdateRowSource.None".
- Assign the SalesLoftCommand objects to the SalesLoftDataAdapter.
- Add the parameters to the command.
- Call the SalesLoftDataAdapter'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 SalesLoftDataAdapter'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#
SalesLoftDataAdapter adapter = new SalesLoftDataAdapter(); using (SalesLoftConnection conn = new SalesLoftConnection("InitiateOAuth=GETANDREFRESH;AuthScheme=OAuth;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackUrl=http://localhost:33333;")) { 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); }
VB.NET
Dim adapter As New SalesLoftDataAdapter()
Using conn As New SalesLoftConnection("InitiateOAuth=GETANDREFRESH;AuthScheme=OAuth;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackUrl=http://localhost:33333;")
conn.Open()
adapter.InsertCommand = conn.CreateCommand()
adapter.InsertCommand.CommandText = "INSERT INTO Accounts (Id) 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)
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#
SalesLoftDataAdapter adapter = new SalesLoftDataAdapter(); using (SalesLoftConnection conn = new SalesLoftConnection("InitiateOAuth=GETANDREFRESH;AuthScheme=OAuth;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackUrl=http://localhost:33333;")) { conn.Open(); adapter.UpdateCommand = conn.CreateCommand(); adapter.UpdateCommand.CommandText = "UPDATE Accounts SET Name=@Name WHERE Id=@Id"; adapter.UpdateCommand.Parameters.Add("@Name", "Name"); adapter.UpdateCommand.Parameters.Add("@Id", "Id"); adapter.UpdateCommand.UpdatedRowSource = UpdateRowSource.None; DataTable batchDataTable = new DataTable(); batchDataTable.Columns.Add("Name", typeof(string)); batchDataTable.Rows.Add("Jon Doe"); batchDataTable.Rows.Add("John"); adapter.UpdateBatchSize = 2; adapter.Update(dataTable); }
VB.NET
Dim adapter As New SalesLoftDataAdapter()
Using conn As New SalesLoftConnection("InitiateOAuth=GETANDREFRESH;AuthScheme=OAuth;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackUrl=http://localhost:33333;")
conn.Open()
adapter.UpdateCommand = conn.CreateCommand()
adapter.UpdateCommand.CommandText = "UPDATE Accounts SET Name=@Name WHERE Id=@Id"
adapter.UpdateCommand.Parameters.Add("@Name", "Name")
adapter.UpdateCommand.Parameters.Add("@Id", "Id")
adapter.UpdateCommand.UpdatedRowSource = UpdateRowSource.None
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(dataTable)
End Using
