In This Topic

Syntax

'Declaration
 
Public Shadows Property SelectCommand As BigcommerceCommand

public new BigcommerceCommand SelectCommand {get; set;}

Property Value

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

csharp

public void CreateDataAdapter(BigcommerceConnection bigcommerceConnection)
{
  BigcommerceDataAdapter myAdapter = new BigcommerceDataAdapter();
  myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
  DataSet myDataSet = new DataSet();
  myAdapter.SelectCommand = new BigcommerceCommand("SELECT id, lastname FROM customers", bigcommerceConnection);
  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 bigcommerceConnection As BigcommerceConnection)
  Dim myAdapter As BigcommerceDataAdapter = New BigcommerceDataAdapter
  myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey
  Dim myDataSet As DataSet = New DataSet
  myAdapter.SelectCommand = New BigcommerceCommand("SELECT id, lastname FROM customers", bigcommerceConnection)
  myAdapter.Fill(myDataSet, "customers")
  Dim myTable As DataTable
  Dim myRow As DataRow
  Dim myColumn As DataColumn
  ' Get all data from all tables within the dataset
  For Each myTable In myDataSet.Tables
    For Each myRow In myTable.Rows
      For Each myColumn In myTable.Columns
        Console.Write(myRow(myColumn) & Chr(9))
      Next myColumn
