下面的代码实现向sql server数据库添加图片和文字的功能。
首先，在sql查询分析器中执行下面的语句，以创建表和存储过程。
drop table person
go
create table person
(
personid int identity,
personemail varchar(255),
personname varchar(255),
personsex char(1),
persondob datetime,
personimage image,
personimagetype varchar(255)
)
drop proc sp_person_isp
go
create proc sp_person_isp
@personemail varchar(255),
@personname varchar(255),
@personsex char(1),
@persondob datetime,
@personimage image,
@personimagetype varchar(255)
as
begin
insert into person
(personemail, personname, personsex,
persondob, personimage, personimagetype)
values
(@personemail, @personname, @personsex,
@persondob, @personimage, @personimagetype)
end
go
下面就是完整的代码，拷贝即可运行：
