老话题了,不多说了看代码吧
测试表
CREATE TABLE IF NOT EXISTS `test` (
`id` int(11) NOT NULL auto_increment,
`sort` int(11)
`title` varchar(50),
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=gb2312 AUTO_INCREMENT=1 ;
存储过程代码
DELIMITER $$;
DROP PROCEDURE IF EXISTS `sp_page`$$
CREATE PROCEDURE `sp_page`(
in _pagecurrent int,/*当前页*/
in _pagesize int,/*每页的记录数*/
in _ifelse varchar(1000),/*显示字段*/
in _where varchar(1000),/*条件*/
in _order varchar(1000)/*排序*/
)
COMMENT '分页存储过程'
BEGIN
if _pagesize<=1 then
set _pagesize=20;
end if;
if _pagecurrent < 1 then
set _pagecurrent = 1;
end if;
set @strsql = concat('select ',_ifelse,' from ',_where,' ',_order,' limit ',_pagecurrent*_pagesize-_pagesize,',',_pagesize);
prepare stmtsql from @strsql;
execute stmtsql;
deallocate prepare stmtsql;
set @strsqlcount=concat('select count(1) as count from ',_where);/*count(1) 这个字段最好是主键*/
prepare stmtsqlcount from @strsqlcount;
execute stmtsqlcount;
deallocate prepare stmtsqlcount;
END$$
DELIMITER ;$$
调用代码
调用例1 call sp_Page(1,3,'*','test','order by id desc');
调用例2 call sp_Page(1,3,'*','test where sort=1','order by id desc');
调用例3 call sp_Page(1,3,'id,title','test where sort=1','order by id desc');
