oracle根据多个条件分别修改符合条件的记录

declare      i number;     temp_sum number;    temp_hfmpcode temptable.pubname%type;  --temptable.pubname%type指的是temptable表的pubname字段的类型    temp_fullname temptable.pubcode%type;begin     select count(*) into temp_sum from temptable b;    i := 1; while i<=temp_sum loop          --1、查询            select t.pubname into temp_hfmpcode from (select rownum rn,b.* from temptable b order by b.pubname) t where t.rn between i and i;            select t.pubcode into temp_fullname from (select rownum rn,b.* from temptable b order by b.pubname) t where t.rn between i and i;            --2、更新            update r_pubinfo t set t.hfmpcode=temp_hfmpcode where t.fullname=temp_fullname;            i := i+1; end loop; end; 

以上代码在sql/plus直接运行即可
