Connection (ADO - WFC 語法)
套件 com.ms.wfc.data
建構函式
public Connection()
public Connection(String connectionstring)
方法
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)
executeUpdate 方法是特殊的案例方法，會使用特定參數，呼叫基礎 ADO execute 方法。 executeUpdate 方法不支援傳回 Recordset 物件，因此會將execute 方法的 options 參數修改為 AdoEnums.ExecuteOptions.NORECORDS。 當 execute 方法完成後，其更新後的 RecordsAffected 參數，將會回傳給 executeUpdate 方法，最終以 int 傳回。
