在sqlserver2000中使用分区表和分区视图
用分区表和分区视图有什么好处,这里就不多说了.顺便说一句就是2000中的分区表和分区视图是伪分区,在2005中才实现了真正高性能的分区表. diary表太大了,查询起来很慢,假如diary表有200多W数据. 1/建立分区表: 将diary表分离成5个表: diary1/diary2/diary3/diary4/diary5,50万用户一个表. select * into diary1 from diary where diary_id between 1 and 500000; . . select * into diary1 from diary where diary_id between 1500001 and 2000000; select * into diary1 from diary where diary_id >2000000; --其实就是把一张表在物理上分成了5个. 2/建立分区视图: CREATE VIEW diaryview AS SELECT * FROM diary1 UNION ALL SELECT * FROM diary2 UNION ALL SELECT * FROM diary3 UNION ALL SELECT * FROM diary4 UNION ALL SELECT * FROM diary5 然后当用户查询时,只给他们使用视图的权限,这样对于他们来说,就还和一张表一样了.
