查询分页：语句1性能提升10倍多，只是因为多了个top关键字，很不理解啊!!!!
1.查询时间1s内,r_object_id主键
select top 100 * from (
select all doc.r_object_id objid,doc.name,doc.number, doc.cuid, doc.r_creation_date, doc.security, doc.bordline, doc.twicedline, doc.dline, doc.keynum, doc.creator_name,
doc.security_name, doc.dline_name, doc.pid, doc.modifier_name, doc.tblcount, doc.r_modify_date, doc.prjdefid, doc.voldefid, doc.tabledefid, doc.relation_id,
doc.r_object_type r_object_type, doc.bcode bcode, doc.copycount, doc.securityapply, doc.pgholtime, doc.done, doc.disciplineid, doc.disciplineid_name,

cast(row_number() over(order by doc.r_object_id asc ) as int) as dm_rnum
from ps_fld_doctree_document_sp doc
left outer join tabledef00054a9a80001e7d_sp tabdef on (doc.r_object_id=tabdef.recid) where (doc.keynum like n'aaaaaaaaaaaaaaa%' and ((doc.isdel=0) or (doc.isdel=1)) )
and (doc.i_has_folder = 1 and doc.i_is_deleted = 0)
) dm_inline_view_1
where dm_rnum >= 101 and dm_rnum
2.查询时间10s内
