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
