華閱文章網mysql mybatis 分頁查詢語句怎么寫
1、親Mybatis是自己寫Sql語句啊，和Hibernate不一樣。
2、如何知道上面的，你還要知道MySql有一個分頁語句叫limit，如：limit(1,10)；前面一個參數是起始未知，后面一個是查詢多少個。3、Oracle的分頁方法是嵌套子查詢，需要用到rownum這個屬性Sql Server是Top。
分頁例子：Oracle select * from (select emp.*,rownum rn from emp where rownum<9) where rn>3;MySql select * from emp limit startIndex,maxNum。
跪求大家幫忙,用MyBatis如何寫分頁操作,求相關代碼 謝謝 速度-百
MyBatis是自帶分頁的，只要記得使用MyBatis的sqlsession就可以了。
int offset = 100;int limit = 25;RowBounds rowBounds = new RowBounds(offset, limit);List
