Java/JSP中调用SQL Server存储过程完整示例

【引自孟子E章的博客】最近做了个Java的小项目（第一次写Java的项目），到网上搜索了半天，找到了一个比较好点的调用存储过程的例子，而且网上普遍采用的都是setXXX((int parameterIndex, XXX x)的形式。这种形式感觉不是很直观，下面就发布一个完整的采用setXXX(String parameterName, XXX x)的编写方法。创建数据表，存储过程的代码都完整发布。

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] PRIMARY KEY  CLUSTERED 
(
[UserID]
)  ON [PRIMARY] 
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
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代码
