Updating the Data

Use the adapter's Update method to update the data. This overloaded method can take a DataTable as a parameter and will commit all the changes made to the data source. The name of the data table can be passed as an argument and can also be used to update the entire dataset in a more traditional manner. When using a data table as an argument to the Update method, the adapter evaluates the changes that have been made to the data table and executes the appropriate command for each row (INSERT, UPDATE, or DELETE).

The example below updates the WorkspaceId of one of the projects entries.

C#

using (AsanaConnection connection = new AsanaConnection(connectionString)) {
  AsanaDataAdapter dataAdapter = new AsanaDataAdapter(
    "SELECT Id, WorkspaceId FROM projects", connection);

  dataAdapter.UpdateCommand = new AsanaCommand(
    "UPDATE projects SET WorkspaceId = @WorkspaceId " +
    "WHERE Id = @Id", connection);
 
  dataAdapter.UpdateCommand.Parameters.Add(new AsanaParameter("@WorkspaceId", DbType.String, "WorkspaceId"));
  dataAdapter.UpdateCommand.Parameters.Add(new AsanaParameter("@Id", DbType.String, "Id"));
  dataAdapter.UpdateCommand.Parameters[1].SourceVersion = DataRowVersion.Original;

  DataTable table = new DataTable();
  dataAdapter.Fill(table);

  DataRow firstrow = table.Rows[0];
  firstrow["WorkspaceId"] = "Jon Doe";

  dataAdapter.Update(table);

  Console.WriteLine("Rows after update.");
  
  foreach (DataRow row in table.Rows) {
    Console.WriteLine("{0}: {1}", row["Id"], row["WorkspaceId"]);
  }
}

VB.NET

Using connection As New AsanaConnection(connectionString)
  Dim dataAdapter As New AsanaDataAdapter(
    "SELECT Id, WorkspaceId FROM projects", connection)
  
  dataAdapter.UpdateCommand = New AsanaCommand(
    "UPDATE projects SET WorkspaceId = @WorkspaceId " +
    "WHERE Id = @Id", connection)
  
  dataAdapter.UpdateCommand.Parameters.Add(new AsanaParameter("@WorkspaceId", DbType.String, "WorkspaceId"))
  dataAdapter.UpdateCommand.Parameters.Add(new AsanaParameter("@Id", DbType.String, "Id"))
  dataAdapter.UpdateCommand.Parameters(1).SourceVersion = DataRowVersion.Original
  
  Dim table As New DataTable()
  dataAdapter.Fill(table)
  
  Dim firstrow As DataRow = table.Rows(0)
  firstrow("WorkspaceId") = "Jon Doe"
  
  dataAdapter.Update(table)
  
  Console.WriteLine("Rows after update.")
  
  For Each row As DataRow In table.Rows
    Console.WriteLine("{0}: {1}", row("Id"), row("WorkspaceId"))
  Next
End Using
