一个对象的其中一个数据块的DBA号为382524589,那如何根据这个号码来获取到该对象的信息：<BR><TABLE style="BORDER-BOTTOM: rgb(153,153,153) 1px solid; BORDER-LEFT: rgb(153,153,153) 1px solid; BACKGROUND-COLOR: rgb(172,172,172); WIDTH: 100%; FONT-SIZE: 12px; BORDER-TOP: rgb(153,153,153) 1px solid; BORDER-RIGHT: rgb(153,153,153) 1px solid" align=center>
