下文介绍的MySql存储过程是带参数的存储过程(动态执行SQL语句)，该MySql存储过程是根据用户输入的条件和排序方式查询用户的信息，排序条件可以没有调用方式：

　　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;
