贴出程序求救：用vc、oo4o访问oracle数据库时怎么能访问到SD0_GEOMETRY中的东东

<P>ODatabase odb;//定义数据库对象<BR>OStartup();<BR>odb.Open("DB","name","pws");</P>
<P>ODynaset dyn; <BR> dyn.Open(odb,"select M_ID, M_NAME, LOCATION from datamine");<BR> OValue Id;<BR> OValue Name;<BR> OObject SdoGeo ;//sdo_geometry字段<BR> dyn.GetFieldValue(0, ;Id);<BR> dyn.GetFieldValue(1, ;Name);<BR> dyn.GetFieldValue(2, ;SdoGeo);</P>
<P>然后又该怎么做了呢？</P>
<P>还有OObject,OCollect都是什么东东啊，有什么意思？</P>

<P>有个例子</P>
