end

------解决方案--------------------
mysql 写存储过程 一般要先定义定界付  

用 DELEMITER

------解决方案--------------------
drop procedure if exists proc_tblModelInfo_Insert
DELIMITER $$
create procedure proc_tblModelInfo_Insert(
out ID int,
vPersonID int,
vFilePath nvarchar(256)
)
begin
  insert into ModelInfo(PersonID,FilePath) values(vPersonID,vFilePath);
  set ID = (select max('id') from ModelInfo);
END$$
DELIMITER ;

细节问题，多加注意
在drop procedure if exists proc_tblModelInfo_Insert 后面加分号测不过找我！
应该这下面这样
===============================
drop procedure if exists proc_tblModelInfo_Insert ;  //这里需要以分号结束好的
DELIMITER $$

create procedure proc_tblModelInfo_Insert(
out ID int,
vPersonID int,
vFilePath nvarchar(256)
)
begin
  insert into ModelInfo(PersonID,FilePath) values(vPersonID,vFilePath);
  set ID = (select max('id') from ModelInfo);
END $$
DELIMITER ;
=========================================================
