本文章旨在介绍如何使用最新JDBC连接SqlServer2005数据库

一、下载安装
1、SqlServer 2005 Express Edition
   下载:
[url]http://msdn.microsoft.com/vstudio/express/sql/download/[/url]
   安装完数据库后设置ICP/IP协议启动,具体如下:
   (1)打开SQL Server Configuration Manager
   (2)转到SQL Server 2005 Network Configuration->Protocols for SQLEXPRESS
   (3)将TCP/IP设置为Enabled(启用)
   (4)双击TCP/IP项,转到IP Addresses页
   (5)IP All中设置TCP Port为1433
   (6)重新启动服务
2、SqlServer2005数据库JDBC驱动
   下载:
[url]http://download.microsoft.com/download/d/2/e/d2e1ffb6-2cfa-4a62-a22d-a413cce93118/Download_SQL_JDBC_Driver.htm[/url]
   安装或者解压,取得sqljdbc.jar文件,该文件即为JDBC驱动。将sqljdbc.jar放到classpath。(web application中放在WEB-INF/lib下)

二、连接数据库SqlServer2005的java代码
1、在tempdb中创建测试数据表格
use tempdb
CREATE TABLE dbo.Table_1
(
ID bigint NOT NULL,
NAME varchar(20) NOT NULL,
EMAIL varchar(50) NULL
) ON [PRIMARY]

2、测试使用数据库连接
   下面代码创建了一个连接数据库连接,及使用连接操作数据库
/*
* 创建日期 2006-6-1
*/
package cn.afss.common.web.test;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

import org.apache.log4j.Logger;

/**
* @author Amei
* Amei's FreeSky Studio
*/
public class TestConnSql2k5Bean {
/**
* Log4J Logger for this class
*/
private static final Logger logger =
Logger.getLogger(TestConnSql2k5Bean.class);
private Connection conn = null;

public TestConnSql2k5Bean() {
super();
}

public void getConnection() {
try {
   Class
    .forName("com.microsoft.sqlserver.jdbc.SQLServerDriver")
    .newInstance();
   String URL = "jdbc:sqlserver://localhost:1433;DatabaseName=tempdb";
   String USER = "sa"; // 根据你自己设置的数据库连接用户进行设置
   String PASSWORD = "sa"; // 根据你自己设置的数据库连接密码进行设置
   conn = DriverManager.getConnection(URL, USER, PASSWORD);
} catch (java.lang.ClassNotFoundException ce) {
   logger.error("Get Connection error:", ce);
} catch (java.sql.SQLException se) {
   logger.error("Get Connection error:", se);
} catch (Exception e) {
   logger.error("Get Connection error:", e);
}
}

public void testConnection() {
if (conn == null)
   this.getConnection();
try {
   String sql = "SELECT * FROM TABLE_1";
   Statement stmt = conn.createStatement();
   ResultSet rs = stmt.executeQuery(sql);
   while (rs.next()) {
    logger.debug(rs.getString("ID"));
    logger.debug(rs.getString("NAME"));
    logger.debug(rs.getString("EMAIL"));
   }
   rs.close();
   stmt.close();
} catch (SQLException e) {
   logger.error(e.getMessage(), e);
} finally {
   if (conn != null)
    try {
     conn.close();
    } catch (SQLException e) {
    }
}
}
public static void main(String[] args) {
TestConnSql2k5Bean bean = new TestConnSql2k5Bean();
bean.testConnection();
}
}

三、Sql Server2000和2005的连接代码区别
   写连接代码时需要注意2000和2005的不同:
1、连接SqlServer2000
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
URL = "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=tempdb";
2、连接SqlServer2005
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
URL = "jdbc:sqlserver://localhost:1433;DatabaseName=tempdb";

注:详细使用请参考MS JDBC中的官方文档。
结束。

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
