    SalesforceCommand Class
    In This Topic
    Represents a SQL statement or stored procedure to execute against Salesforce.com or Database.com.
    Syntax
    Remarks
    The SalesforceCommand class provides the following methods for executing commands against the Salesforce.com or Database.com database:
    Item Description
    ExecuteReader Executes commands that return rows.
    ExecutePageReader Returns a specific subset of rows when paging through the results of a query.
    ExecuteNonQuery Executes SQL commands such as INSERT, DELETE, UPDATE.
    ExecuteScalar Retrieves a single value (for example, an aggregate value) from a data source.

    If execution of the command results in a fatal SalesforceException, the SalesforceConnection may close. However, the user can reopen the connection and continue.

    Example
    The following example uses the ExecuteReader method of SalesforceCommand, along with SalesforceDataReader and SalesforceConnection, to select rows from a table.
    public void ReadMyData(string myConnString) 
    { 
            string mySelectQuery = "SELECT ID, Name FROM Account"; 
            SalesforceConnection salesforceConnection = new SalesforceConnection(myConnString); 
            SalesforceCommand salesforceCommand = new SalesforceCommand(mySelectQuery,salesforceConnection); 
            salesforceConnection.Open(); 
            SalesforceDataReader salesforceReader; 
            salesforceReader = salesforceCommand.ExecuteReader(); 
            // Always call Read before accessing data. 
            while (salesforceReader.Read()) { 
                    Console.WriteLine(salesforceReader.GetString(0) + ", " + salesforceReader.GetString(1)); 
            } 
            // always call Close when done reading. 
            salesforceReader.Close(); 
            // Close the connection when done with it. 
            salesforceConnection.Close(); 
    }
    Public Sub ReadMyData(myConnString As String)
            Dim mySelectQuery As String = "SELECT ID, Name FROM Account"
            Dim salesforceConnection As New SalesforceConnection(myConnString)
            Dim salesforceCommand As New SalesforceCommand(mySelectQuery, salesforceConnection)
            salesforceConnection.Open()
            Dim salesforceReader As SalesforceDataReader
            salesforceReader = salesforceCommand.ExecuteReader()
            ' Always call Read before accessing data. 
            While salesforceReader.Read()
                    Console.WriteLine(salesforceReader.GetString(0) & ", " & salesforceReader.GetString(1))
            End While
            ' always call Close when done reading. 
            salesforceReader.Close()
            ' Close the connection when done with it. 
            salesforceConnection.Close()
    End Sub
