实例讲解JSP调用SQL Server的存储过程

文章作者:网友投稿 发布时间:2008-10-07 来源:网络

JSP调用SQL Server存储过程的实例: 创建表: 以下为引用的内容: CREATE TABLE [BookUser] ( [UserID] [int] IDENTITY (1, 1) NOT NULL , [UserName] [varchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL , [Title] [nvarchar] (50)

JSP调用SQL Server存储过程的实例:

创建表:

以下为引用的内容:
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] PRIMARY KEY CLUSTERED
(
[UserID]
) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

创建存储过程:


以下为引用的内容:
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代码:

以下为引用的内容:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ page import = "java.sql.*"%>
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
