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。
<![CDATA[
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：
