总结下主流的MYSQL,sqlSever 和oracle的数据库的分页代码,如下:
MySQL:select * from TableName where …… limit start_th , count_num; SqlSever:select top count_num from TableName where id not in (select top count_num from TableName where ……);
Oracle:select t2.* from (select t1.* ,rownum rn from (select * from TabbleName where ……) t1 where rownum <=endline ) t2 where t2.rn>=start_line;
oracle 的条件筛选都放在最内层进行第一层筛选,剔除末尾的(第二层),剔除头部的(第三层)
供大家参考!
