ASP.NET2.0调用MySql的存储过程
MYSQL 从5.0开始便加入了存储过程,因为它出现的时间还不是很久,现在有很多都在问,MYSQL存储过程怎么建立,下我就我所理解的建了一个.在asp.net2.0下调用非常方法,跟SQL差不多,但也有少少差别,下面就是MYSQL一个分页的的存储过程;MYSQL的limite给我们带来很大的方便.不要写太多的代码!
DELIMITER $$;
DROP PROCEDURE IF EXISTS `mytest`.`MyPage`$$
CREATE DEFINER=`root`@`localhost` PROCEDURE `MyPage`(
tableName varchar(100),
fieldsName VARCHAR(100),
pageIndex int,
pageSize int,
sortName VARCHAR(500),
strWhere varchar(500)
)
BEGIN
DECLARE fieldlist VARCHAR(200);
if fieldsName=''||fieldsName=null THEN
set fieldlist='*';
else
set fieldlist=fieldsName;
end if;
if strWhere=''||strWhere=null then
if sortName=''||sortName=null then
set @strSQL=concat('select ',fieldlist,' from ' , tableName,' limit ',(pageindex-1)*pageSize,',',pageSize);
else
set @strSQL=concat('select ',fieldlist,' from ' , tableName,' order by ',sortName,' limit ',(pageindex-1)*pageSize,',',pageSize);
end if;
else
if sortName=''||sortName=null then
set @strSQL=concat('select ',fieldlist,' from ' , tableName,' where ',strWhere,' limit ',(pageindex-1)*pageSize,',',pageSize);
else
set @strSQL=concat('select ',fieldlist,' from ' , tableName,' where ',strWhere,' order by ',sortName,' limit ',(pageindex-1)*pageSize,',',pageSize);
end if;
end if;
PREPARE stmt1 FROM @strSQL;
EXECUTE stmt1;
DEALLOCATE PREPARE stmt1;
END$$
DELIMITER ;$$
Asp.net2.0调用方法.下次给出来…….
