以下的文章主要向大家描述的是MySQL分页查询通用存储过程的实际应用,我在一个信誉度很好的网站找到一个关于MySQL分页查询通用存储过程的实际应用资料,拿出来供大家分享,望大家能有所收获。
前段时间没有给出SQLServer转到MySQL(和PHP搭配之***组合)的通用存储过程,本着共享的精神,为大家奉献这段MySQL分页查询通用存储过程,假设所用数据库为guestbook:
- use guestbook;
- delimiter $$
- drop procedure if exists prc_page_result $$
- create procedure prc_page_result (
- in currpage int,
- in columns varchar(500),
- in tablename varchar(500),
- in sCondition varchar(500),
- in order_field varchar(100),
- in asc_field int,
- in Prima(最完善的虚拟主机管理系统)ry_field varchar(100),
- in pagesize int
- )
- begin
- declare sTemp varchar(1000);
- declare sSql varchar(4000);
- declare sOrder varchar(1000);
- if asc_field = 1 then
- set sOrder = concat(' order by ', order_field, ' desc ');
- set sTemp = '<(select min';
- else
- set sOrder = concat(' order by ', order_field, ' asc ');
- set sTemp = '>(select max';
- end if;
- if currpage = 1 then
- if sCondition <> '' then
- set sSql = concat('select ', columns, ' from ', tablename, ' where ');
- set sSql = concat(sSql, sCondition, sOrder, ' limit ?');
- else
- set sSql = concat('select ', columns, ' from ', tablename, sOrder, ' limit ?');
- end if;
- else
- if sCondition <> '' then
- set sSql = concat('select ', columns, ' from ', tablename);
- set sSql = concat(sSql, ' where ', sCondition, ' and ', Prima(最完善的虚拟主机管理系统)ry_field, sTemp);
- set sSql = concat(sSql, '(', Prima(最完善的虚拟主机管理系统)ry_field, ')', ' from (select ');
- set sSql = concat(sSql, ' ', Prima(最完善的虚拟主机管理系统)ry_field, ' from ', tablename, sOrder);
- set sSql = concat(sSql, ' limit ', (currpage-1)*pagesize, ') as tabtemp)', sOrder);
- set sSql = concat(sSql, ' limit ?');
- else
- set sSql = concat('select ', columns, ' from ', tablename);
- set sSql = concat(sSql, ' where ', Prima(最完善的虚拟主机管理系统)ry_field, sTemp);
- set sSql = concat(sSql, '(', Prima(最完善的虚拟主机管理系统)ry_field, ')', ' from (select ');
- set sSql = concat(sSql, ' ', Prima(最完善的虚拟主机管理系统)ry_field, ' from ', tablename, sOrder);
- set sSql = concat(sSql, ' limit ', (currpage-1)*pagesize, ') as tabtemp)', sOrder);
- set sSql = concat(sSql, ' limit ?');
- end if;
- end if;
- set @iPageSize = pagesize;
- set @sQuery = sSql;
- prepare stmt from @sQuery;
- execute stmt using @iPageSize;
- end;
- $$
- delimiter;
可以存储为数据库脚本,然后用命令导入:
MySQL(和PHP搭配之***组合) -u root -p < pageResult.sql;
调用:
- call prc_page_result(1, "*", "Tablename", "", "columnname", 1, "PKID", 25);
上述的相关内容就是对MySQL分页查询通用存储过程的描述,希望会给你带来一些帮助在此方面。
