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SQL语句，以创建表和存储过程。

CREATE TABLE Photos (
 [name] varchar(50),
 [photo] image NULL
)
GO

CREATE PROCEDURE sp_InsertPhoto
 @name AS VARCHAR(50),
 @image AS IMAGE
 AS
INSERT INTO Photos ([name],  [photo])
VALUES (@name, @image)
GO
下面就是完整的代码，拷贝即可运行：
