最近用mysql + asp.net来写网站WebSite既然mysql已经支持存储过程了那么像分页这么常用东西当然要用存储过程啦

不过在网上找了些发现都有个特点——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个记录

CREATE PROCEDURE p_pageList

(

m_pageNo ,

m_perPageCnt ,

m_column varchar(1000) ,

m_table varchar(1000) ,

m_condition varchar(1000),

m_orderBy varchar(200) ,

out m_totalPageCnt

)

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) o @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;

IF m_orderBy IS NOT NULL AND m_orderBy <> '' THEN

SET @sql = CONCAT(@sql,' order by ',m_orderBy);

END IF;

SET @sql = CONCAT(@sql, ' limit ', @limitStart, ',', @limitEnd);

PREPARE s_cnt from @sqlCnt;

EXECUTE s_cnt;

DEALLOCATE PREPARE s_cnt;

SET m_totalPageCnt = @pageCnt;


PREPARE record from @sql;

EXECUTE record;

DEALLOCATE PREPARE record;

END
