Exadata上的分页查询性能测试

Exadata上的分页查询性能测试，Exadata上的SMART SCAN STORAGE FULL FIRST ROWS对于没有索引情况下的分页查询可以而节约大量处理时间：   SQL> create table larget tablespace users as select rownum t1, rpad('M',99,'A') t2, rpad('M',99,'A') t3, rpad('M',99,'A') t4 from dual connect by level<=9999999; Table created. select llv.* from ( select rownum rn, ll.* from (select * from larget order by t1 ) ll where rownum<=200) llv where llv.rn<10;
