    說明

    mixed SDO_DAS_Setting::getValue ( void )
    Warning

    本函式是實驗性的。這個函式的行為、名稱、和關於此函式的任何其他文件在未來PHP的發行中可能會在不通知的情況下改變。 使用此函式需自行承擔風險。

    Returns the old value for the changed property. This can be used by a Data Access Service when writing updates to a data source. The DAS uses the old value to detect conflicts by comparing it with the current value in the data source. If they do not match, then the data source has been updated since the data object was originally populated, and therefore writing any new updates risks compromising the integrity of the data.

    參數

    None.
