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：
