from dba_tab_partitions t
where t.table_owner in ('NCCMOLTP') and t.partition_name not like '%410927%') loop
begin
--select count(*) into cnt from tjfrecord partition(aa.partition_name);
execute immediate 'select count(*) from '||aa.table_name ||' partition('||aa.partition_name||')'
into cnt;
if cnt = 0 then
execute immediate 'alter table '||aa.table_name||' drop partition '||aa.partition_name;
end if;
end;
end loop;

where t.table_owner in ('NCCMHIST') and t.subpartition_name not like '%410927%') loop
begin
--select count(*) into cnt from tjfrecord partition(aa.partition_name);
execute immediate 'select count(*) from '||aa.table_name ||' subpartition('||aa.subpartition_name||')'
