下来,设置sqlplus的两个参数:pagesize、linesize。 一页中显示的行数可以使用set pagesize命令设置 一行中显示的字符数可以使用set linesize命令设置 ?...那就是每次进入sqlplus都得重新设置linesize和pagesize,能不能不这样做呢?可以!
from table limit (3-1)*10,10; 二:通过上面的分析,可以得出符合我们自己需求的分页sql格式 mysql分页:select * from 表 limit (pageNo-1)*pageSize...,pageSize; oracle分页:select a.* (select 表....*,rowum rn from 表) a where rn>(pageNo-1)*pageSize and rn <=pageNo*pageSize; 三、 在MyBatis中LIMIT之后的语句不允许的变量不允许进行算数运算...LIMIT (#{pageNo}-1)*#{pageSize},#{pageSize}; // 错误 LIMIT ${(pageNo-1)*pageSize},${pageSize}; (正确
