Conexión (ADO : sintaxis WFC)

package com.ms.wfc.data

Constructor

public Connection()  
public Connection(String connectionstring)  

Métodos

public int beginTrans()  
public void commitTrans()  
public void rollbackTrans()  
public void cancel()  
public void close()  
public com.ms.wfc.data.Recordset execute(String commandText)  
public com.ms.wfc.data.Recordset execute(String commandText, int options)  
public int executeUpdate(String commandText)  
public int executeUpdate(String commandText, int options)  

El método executeUpdate es un método de caso especial que llama al método execute de ADO subyacente con determinados parámetros. El método executeUpdate no admite la devolución de un objeto Recordset , por lo que el parámetrooptions del método execute se modifica con AdoEnums.ExecuteOptions.NORECORDS. Una vez completado el método execute , su parámetro RecordsAffected actualizado se devuelve al método executeUpdate , que finalmente se devuelve como un valor int.
