新老客户大回馈,云服务器低至5折

  最近做了个Java的小项目(第一次写Java的项目哦), 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 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" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<body>

//注意:下面的连接方法采用最新的SQL Server的JDBC,

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.prepareCall(sql);
 java.util.UUID Guid = java.util.UUID.randomUUID();
 String FilePath = application.getRealPath("") "\test\logo.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();
 int returnValue = cmd.getInt(1);
 int UserID = cmd.getInt("UserID");
 if(returnValue == 1)
 {
  out.print("<li>添加成功!");
  out.print("<li>UserID = " UserID);
  out.print("<li>returnValue = " returnValue);
 }
 else
 {
  out.print("<li>添加失败!");
 }
 f.close();
}
catch(Exception ex)
{
 out.print(ex.getLocalizedMessage());
}
finally
{
 try
 {
  if(cmd != null) 
  {
   cmd.close();
   cmd = null;
  }
  if(cn != null)
  {
   cn.close();
   cn = null;
  }
 }
 catch(Exception e)
 {
  e.printStackTrace();
 }
}
%>
