此文章主要向大家講述的是MySQL分頁查詢通用存儲過程,我們前一段時間沒有給出SQLServer轉到MySQL的通用存儲過程,本著與大家共享的精神,為大家奉獻這段MySQL分頁查詢通用存儲過程,假設所用數據庫為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(最完善的虛擬主機管理系統)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(最完善的虛擬主機管理系統)ry_field, sTemp);
- set sSql = concat(sSql, '(', Prima(最完善的虛擬主機管理系統)ry_field, ')', ' from (select ');
- set sSql = concat(sSql, ' ', Prima(最完善的虛擬主機管理系統)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(最完善的虛擬主機管理系統)ry_field, sTemp);
- set sSql = concat(sSql, '(', Prima(最完善的虛擬主機管理系統)ry_field, ')', ' from (select ');
- set sSql = concat(sSql, ' ', Prima(最完善的虛擬主機管理系統)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;
可以存儲為數據庫腳本,然後用命令導入:
MySQL(和PHP搭配之最佳組合) -u root -p < pageResult.sql;
調用:call prc_page_result(1, "*", "Tablename", "", "columnname", 1, "PKID", 25);
以上的相關內容就是對MySQL分頁查詢通用存儲過程的介紹,望你能有所收獲。
