实例讲解JSP调用SQL Server的存储过程
jsp(SUN企业级应用的首选)调用sql server(WINDOWS平台上强大的数据库平台)存储过程的实例：
创建表：
CREATE TABLE [BookUser] (
[UserID] [int] IDENTITY (1, 1) NOT NULL ,
[UserName] [varchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL ,
[Title] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL ,
[Guid] [uniqueidentifier] NOT NULL CONSTRAINT [DF_BookUser_Guid] DEFAULT (newid()),
[BirthDate] [datetime] NOT NULL ,
[Description] [ntext] COLLATE Chinese_PRC_CI_AS NOT NULL ,
[Photo] [image] NULL ,
[Other] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL
CONSTRAINT [DF_BookUser_Other] DEFAULT (默认值),
CONSTRAINT [PK_BookUser] Prima(最完善的虚拟主机管理系统)RY KEY CLUSTERED
(
[UserID]
) ON [Prima(最完善的虚拟主机管理系统)RY]
) ON [Prima(最完善的虚拟主机管理系统)RY] TEXTIMAGE_ON [Prima(最完善的虚拟主机管理系统)RY]
GO
创建存储过程：
CREATE PROCEDURE InsertUser
@UserName varchar(50),
@Title varchar(255),
@Guid uniqueidentifier,
@BirthDate DateTime,
@Description ntext,
@Photo image,
@Other nvarchar(50),
@UserID int output
As
Set NOCOUNT ON
If Exists (select UserID from BookUser Where UserName = @UserName)
RETURN 0
ELSE
Begin
INSERT INTO BookUser (UserName,Title,Guid,BirthDate,Description,Photo,Other)
VALUES(@UserName,@Title,@Guid,@BirthDate,@Description,@Photo,@Other)
SET @UserID = @@IDENTITY
RETURN 1
End
GO
jsp(SUN企业级应用的首选)代码：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ page import = "java.sql.*"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

//注意：下面的连接方法采用sql server(WINDOWS平台上强大的数据库平台)的JDBC，先下载sqlserver驱动。
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String url="jdbc:sqlserver://localhost:1433;databaseName=Book;user=sa;password=";
String sql = "{? = call InsertUser(?,?,?,?,?,?,?,?)}";
Connection cn = null;
CallableStatement cmd = null;
try
{
cn = DriverManager.getConnection(url);
cmd = cn.divpareCall(sql);
java.util.UUID Guid = java.util.UUID.randomUUID();
String FilePath = application.getRealPath("") + " estlogo.gif";
java.io.FileInputStream f = new java.io.FileInputStream(FilePath);
Date rightNow = Date.valueOf("2007-9-9");
cmd.setString("UserName","mengxianhui");
//注意修改这里，存储过程验证了UserName的唯一性。
cmd.setString("Title","孟宪会");
cmd.setString("Guid",Guid.toString());
cmd.setString("BirthDate","2007-9-9");
cmd.setDate("BirthDate",rightNow);
cmd.setString("Description","【孟子E章】");
cmd.setBinaryStream("Photo",f,f.available());
cmd.setString("Other",null);
cmd.registerOutParameter(1,java.sql.Types.INTEGER);
cmd.registerOutParameter("UserID",java.sql.Types.INTEGER);
cmd.execute();
