Connessione (sintassi ADO - WFC)

package com.ms.wfc.data

Costruttore

public Connection()  
public Connection(String connectionstring)  

Metodi

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)  

Il metodo executeUpdate è un metodo case speciale che chiama il metodo execute ADO sottostante con determinati parametri. Il metodo executeUpdate non supporta la restituzione di un oggetto Recordset, pertanto il parametro options del metodo execute viene modificato con AdoEnums.ExecuteOptions.NORECORDS. Al termine del metodo execute , il parametro RecordsAffected aggiornato viene passato al metodo executeUpdate , che viene infine restituito come int.
