最近用mysql + asp.net来写网站,既然mysql已经支持存储过程了,那么像分页这么常用的东西,当然要用存储过程啦
不过在网上找了一些,发现都有一个特点——就是不能传出总记录数,干脆自己研究吧。终于,算是搞出来了,效率可能不是很好,但是我也觉得不错了。贴代码吧直接:也算是对自己学习mysql的一个记录。文章源自很文博客https://www.hinvn.com/很文博客-https://www.hinvn.com/52093.html
- CREATE PROCEDURE p_pageList
- (
- m_pageNo int ,
- m_perPageCnt int ,
- m_column varchar(1000) ,
- m_table varchar(1000) ,
- m_condition varchar(1000),
- m_orderBy varchar(200) ,
- out m_totalPageCnt int
- )
- BEGIN
- SET @pageCnt = 1; -- 总记录数
- SET @limitStart = (m_pageNo - 1)*m_perPageCnt;
- SET @limitEnd = m_perPageCnt;
- SET @sqlCnt = CONCAT('select count(1) into @pageCnt from ',m_table); -- 这条语句很关键,用来得到总数值
- SET @sql = CONCAT('select ',m_column,' from ',m_table);
- IF m_condition IS NOT NULL AND m_condition <> '' THEN
- SET @sql = CONCAT(@sql,' where ',m_condition);
- SET @sqlCnt = CONCAT(@sqlCnt,' where ',m_condition);
- END IF;

- PREPARE s_cnt from @sqlCnt;
- EXECUTE s_cnt;
- DEALLOCATE PREPARE s_cnt;
- SET m_totalPageCnt = @pageCnt;
- PREPARE record from @sql;
- EXECUTE record;
