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。
复制代码 代码如下:
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;
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
