In This Topic

Gets or sets a Dynamics CRM statement used to select records in the data source.

Syntax

C#

'Declaration
 
Public Shadows Property SelectCommand As DynamicsCommand

public new DynamicsCommand SelectCommand {get; set;}

Property Value

A DynamicsCommand that is used during a fill operation to select records from the data source for placement in the System.Data.DataSet.

Remarks

When SelectCommand is assigned to a previously created DynamicsCommand, the DynamicsCommand is not cloned. Instead, the SelectCommand maintains a reference to the previously created DynamicsCommand object.

If SelectCommand does not return any rows, no tables are added to the System.Data.DataSet, and no exception is raised.

This property supports the InterForm technology.

Example

The following example creates a DynamicsDataAdapter, sets some of its properties, retrieves data from a table, and displays it.

csharp

public void CreateDataAdapter(DynamicsConnection dynamicsConnection)
{
  DynamicsDataAdapter myAdapter = new DynamicsDataAdapter();
  myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
  DataSet myDataSet = new DataSet();
  myAdapter.SelectCommand = new DynamicsCommand("SELECT contactid, lastname FROM contact", dynamicsConnection);
  myAdapter.Fill(myDataSet,"contact");
  //Get all data from all tables within the dataset
  foreach(DataTable myTable in myDataSet.Tables)
  {
    foreach(DataRow myRow in myTable.Rows)
    {
      foreach (DataColumn myColumn in myTable.Columns)
      {
        Console.Write(myRow[myColumn]+"\t");
      }
      Console.WriteLine();
    }
    Console.WriteLine();
  }
}

Visual Basic

Public Sub CreateDataAdapter(ByVal dynamicsConnection As DynamicsConnection)

  myAdapter.Fill(myDataSet, "contact")
  Dim myTable As DataTable

  ' Get all data from all tables within the dataset
