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

JIRADataAdapter adapter = new JIRADataAdapter();

using (JIRAConnection conn = new JIRAConnection("User=admin;APIToken=myApiToken;Url=https://yoursitename.atlassian.net")) {
  conn.Open();
  adapter.InsertCommand = conn.CreateCommand();
  adapter.InsertCommand.CommandText = "INSERT INTO Projects (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("Test Project.");
  batchDataTable.Rows.Add("New project!");
  adapter.UpdateBatchSize = 2;
  adapter.Update(batchDataTable);

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

Using conn As New JIRAConnection("User=admin;APIToken=myApiToken;Url=https://yoursitename.atlassian.net")
  conn.Open()
  adapter.InsertCommand = conn.CreateCommand()
  adapter.InsertCommand.CommandText = "INSERT INTO Projects (Key) 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("New project!")
  batchDataTable.Rows.Add("Test Project.")
  adapter.UpdateBatchSize = 2
  adapter.Update(batchDataTable)

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