In This Topic

Syntax

'Declaration
 
Public Shadows Property SelectCommand As SalesforceCommand

public new SalesforceCommand SelectCommand {get; set;}

Property Value

A SalesforceCommand 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 SalesforceCommand, the SalesforceCommand is not cloned. Instead, the SelectCommand maintains a reference to the previously created SalesforceCommand object.

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

Example

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

csharp

public void CreateDataAdapter(SalesforceConnection salesforceConnection) 
{ 
        SalesforceDataAdapter myAdapter = new SalesforceDataAdapter(); 
        myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey; 
        DataSet myDataSet = new DataSet(); 
        myAdapter.SelectCommand = new SalesforceCommand("SELECT ID, Name FROM Account", salesforceConnection); 
        myAdapter.Fill(myDataSet,"Accounts"); 
        //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 salesforceConnection As SalesforceConnection)
        Dim myAdapter As SalesforceDataAdapter = New SalesforceDataAdapter
        myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey
        Dim myDataSet As DataSet = New DataSet
        myAdapter.SelectCommand = New SalesforceCommand("SELECT ID, Name FROM Account", salesforceConnection)
        myAdapter.Fill(myDataSet, "Accounts")
        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
                        Console.WriteLine()
                Next myRow
                Console.WriteLine()
