删除GeoDadabase中数据的问题

<P>我想删除一个GeoDatabase中的数据，但是没有删除掉，该如何处理呢？谢谢了。</P>
<P>我的代码如下。</P>
<P>  ITablePtr ipTable = GetGeoTable(lpTableName);//可以获取到该指针</P>
<P>方法一：</P>
<P>  IQueryFilterPtr ipQueryFilter(CLSID_QueryFilter);<BR>  ipQueryFilter->put_WhereClause((_bstr_t)lpFilter);<BR>  <BR>  ipTable->DeleteSearchedRows(ipQueryFilter);</P>
<P>方法二：</P>
<P>  ICursorPtr ipCursor;<BR>  ipTable->Update(ipQueryFilter,VARIANT_FALSE,;ipCursor);<BR>  <BR>  IRowPtr ipRow;<BR>  ipCursor->NextRow(;ipRow);<BR>  while (ipRow != NULL)<BR>  {<BR>   HRESULT hr = ipCursor->DeleteRow();</P>
<P>   // 或者 HRESULT hr ＝ ipRow->Delete();<BR>   <BR>   HRESULT hr2 = ipCursor->NextRow(;ipRow);<BR>  }<BR></P>
<P>下次再对Table查询的时候还有该记录。<BR><BR></P>

<P>谢谢你！我这里对一个Feature进行操作的时候也是可以的。</P>
<P>对Table 操作时提示The Requested operation is invaliad on a closed state.</P>
<P>还没有找到原因。：（</P>

<P>这是VB中删除要素的例子，希望对你能有所帮助：</P>
<P>  Dim pWorkspaceEdit As IWorkspaceEdit<BR>  Dim pFeature As IFeature<BR>  Dim pActiveView As IActiveView<BR>  <BR>  On Error GoTo DeleteSelectedFeatures_err<BR>  <BR>  If m_pCurrentLayer Is Nothing Then Exit Sub<BR>          <BR>  ' If there are no features currently selected then nothing to do<BR>  Set pFeatureCursor = GetSelectedFeatures<BR>  If pFeatureCursor Is Nothing Then Exit Sub</P>
<P>'  m_pMap.ClearSelection</P>
<P>  ' Loop over the selected features deleting each in turn<BR>  Set pWorkspaceEdit = GetWorkspaceEdit<BR>  pWorkspaceEdit.StartEditOperation<BR>  Set pFeature = pFeatureCursor.NextFeature<BR>  While Not pFeature Is Nothing<BR>    pFeature.Delete<BR>    Set pFeature = pFeatureCursor.NextFeature<BR>  Wend<BR>  pWorkspaceEdit.StopEditOperation<BR></P>
