如何在SAS9.4中获得像OLAPDataSetInterface这样的对象

libname mylib 'path_to_your_library';

proc olap data=mylib.mydata;
   cube mycube;
   dimensions dim1 dim2;
   measures measure1 measure2;
run;

data _null_;
   set sashelp.vtable (where=(libname='MYLIB' and memname='MYCUBE'));
   if upcase(engine)='OLAP' then do;
      rc=metadata_getnasn(metadata_getid('OMSOBJECT'), 'OLAPDataSetInterface', 1, dsid);
      if rc=0 then do;
         put 'OLAPDataSetInterface object obtained successfully.';
         /* 在这里可以使用OLAPDataSetInterface对象进行进一步的操作 */
      end;
      else put 'Failed to obtain OLAPDataSetInterface object.';
   end;
run;
