Syntax

'Declaration
 
Public Shadows Property SelectCommand As MagentoCommand

public new MagentoCommand SelectCommand {get; set;}

Property Value

A MagentoCommand 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 MagentoCommand, the MagentoCommand is not cloned. Instead, the SelectCommand maintains a reference to the previously created MagentoCommand 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 MagentoDataAdapter, sets some of its properties, retrieves data from a table, and displays it.

csharp

public void CreateDataAdapter(MagentoConnection adobe commerceConnection)
{
  MagentoDataAdapter myAdapter = new MagentoDataAdapter();
  myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
  DataSet myDataSet = new DataSet();
  myAdapter.SelectCommand = new MagentoCommand("SELECT customer_id, lastname FROM Customers", adobe commerceConnection);
  myAdapter.Fill(myDataSet,"Customers");
  //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 adobe commerceConnection As MagentoConnection)

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

  ' Get all data from all tables within the dataset
  For Each myTable In myDataSet.Tables
