MySql存储过程带参数处理方式_MySQL

　　call GetUsersDynamic('age<=30','');

/********动态查询用户的信息********/    
CREATE PROCEDURE GetUsersDynamic(WhereCondition varchar(500),OrderByExpress varchar(100))    
begin    
declare stmt varchar(2000);    
if LENGTH(OrderbyExpress)>0 then    
begin    
     set @sqlstr=concat('select id,name,password,age,getdate(adddate) as AddDate from users where ',WhereCondition,' order by ',OrderByExpress);    
end;    
else    
begin    
     set @sqlstr=concat('select id,name,password,age,getdate(adddate) as AddDate from users where ',WhereCondition);    
end;    
end if;    
prepare stmt from @sqlstr;    
execute stmt;    
end;   

　　getdate()是一个自定义的函数，作用是返回日期的短格式

CREATE DEFINER=`root`@`localhost` FUNCTION `getdate`($date datetime) RETURNS varchar(50) CHARSET latin1    
return date_format($date,'%Y-%m-%d');  

　　动态插入数据的MySql存储过程，(注意四个单引号表示一个一引号)：

CREATE DEFINER=`root`@`localhost` PROCEDURE `InsertUser`(in name2 varchar(50),in password2 varchar(32),in age2 int,in adddate2 datetime)    
begin    
DECLARE stmt varchar(2000);    
set @sqlstr=concat('insert into users(name,password,age,adddate) values(');    
set @sqlstr=concat(@sqlstr,'''',name2,'''',',','''',password2,'''',',',age2,',','''',adddate2,'''',')');    
prepare stmt from @sqlstr;    
execute stmt;    
end;
