實例講解JSP調用SQL Server的存儲過程

編輯:關於JSP

    JSP調用SQL Server存儲過程的實例:


    創建表:


    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 ('默認值'),
        CONSTRAINT [PK_BookUser] PRIMARY KEY  CLUSTERED 
        (
            [UserID]
        )  ON [PRIMARY] 
    ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
    GO

     

     

     

    創建存儲過程:


    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代碼:


    <%@ 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">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    </head>
    <body>
    <%
    //注意:下面的連接方法采用SQL Server的JDBC,先下載sqlserver驅動。
    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("") + "testlogo.gif";
        java.io.FileInputStream f = new java.io.FileInputStream(FilePath); 
        Date rightNow = Date.valueOf("2007-9-9");
        cmd.setString("UserName","mengxianhui");  
        //注意修改這裡,存儲過程驗證了UserName的唯一性。
        cmd.setString("Title","孟憲會");
    &nb


    sp;   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>添加失敗!");
        }
        f.close();
    }
    catch(Exception ex)
    {
        out.print(ex.getLocalizedMessage());
    }
    finally
    {
        try
        {
            if(cmd != null)
            {
                cmd.close();
                cmd = null;
            }
            if(cn != null)
            {

                cn = null;
            }
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }
