Java/JSP 中调用 SQL Server 存储过程完整示例

    最近做了个 Java 的小项目，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：

  〈%@ page import = “java.sql.*“%〉
