向SQL Server数据库添加图片和文字的功能

来源：互联网发布：金庸群侠传mac脚本编辑：程序博客网时间：2024/04/30 00:36

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 PersonGoCreate 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_ispGoCreate Proc sp_person_isp@PersonEmail Varchar(255),@PersonName Varchar(255),@PersonSex Char(1),@PersonDOB DateTime,@PersonImage Image,@PersonImageType Varchar(255)AsBegin Insert into Person (PersonEmail, PersonName, PersonSex, PersonDOB, PersonImage, PersonImageType) Values (@PersonEmail, @PersonName, @PersonSex, @PersonDOB, @PersonImage, @PersonImageType)EndGo

下面就是完整的代码，拷贝即可运行：
