JAVA sql2000 连接细节

1、首先要记得sql2000 要打上sp3以上的补丁.(建议用sp4) 2、装上SQL Server 2000 Driver for JDBC Service Pack 3 下载地址:http://www.microsoft.com/downloads/details.aspx?FamilyId=07287B11-0502-461A-B138-2AA54BFDC03A&displaylang=en 3、安装完SQL Server 2000 Driver for JDBC Service Pack 3，它默认安装在C:/Program Files/Microsoft SQL Server 2000 Driver for JDBC 里，在C:/Program Files/Microsoft SQL Server 2000 Driver for JDBC/lib 这个目录里有三个jar文件: msbase.jar,mssqlserver.jar,msutil.jar，一定要记得把这三个文件copy到你所安装的jdk下的jre目里，这里我以的我的安装配置进行解说: 我的jdk是jdk1.5.0_09，默认安装在: C:/Program Files/Java 里，在这个C:/Program Files/Java目录下有两个文件夹: jdk1.5.0_09 目录 和 jre1.5.0_09目录， 前面说的的那三个jar文件一定要copy到jdk1.5.0_09目录里下的jre目录下的lib目录下的ext目录下，我这里的完整路径为: C:/Program Files/Java/jdk1.5.0_09/jre/lib/ext 4、设置classpath，把这个三个jar文件，加进去 5、sql2000要设置为混合登录模式(windows 和 sql) ----------------------------------------------------------------------------------------------------------- 调用示例JAVA代码 ---------------------------------------------------------------------------------------------------------- import java.sql.SQLException; import java.sql.Connection; import java.sql.DriverManager; import java.sql.PreparedStatement; import java.sql.Statement; import java.sql.ResultSet; //import java.*; class CourseAppl { private Connection conn; private String url; private String serverName; private String portNumber; private String databaseName; private String userName; private String password; private String sql; CourseAppl() { url = "jdbc:microsoft:sqlserver://"; serverName = "localhost"; portNumber = "1433"; databaseName = "test"; userName = "sa"; password = ""; } private String getConnectionUrl() { //System.out.println (url + serverName + ":" // + portNumber + ";databaseName=" //+ databaseName + ";"); return url + serverName + ":" + portNumber + ";databaseName=" + databaseName + ";"; } private Connection getConnection() { try { System.out.println (getConnectionUrl()); Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver"); //Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDrive"); conn = DriverManager.getConnection(getConnectionUrl(),userName,password); if(conn != null) { System.out.println ("数据库连接成功!"); } }catch(Exception ce) { ce.printStackTrace(); System.out.println ("getConnection() 内部错误跟踪:" + ce.getMessage()); } return conn; } public void display() { try { conn = getConnection(); PreparedStatement pstmt = conn.prepareStatement("update friends set "+ "salary = ? where name like ?"); pstmt.setInt(1,10000); pstmt.setString(2,"李四"); pstmt.executeUpdate(); System.out.println ("李四的记录已经被更新!!"); Statement stmt = conn.createStatement(); ResultSet rs = stmt.executeQuery("select * from friends"); if(!rs.next()) { System.out.println ("空表，没有数据!!"); }else { System.out.print(rs.getString(1) + "/t"); System.out.print(rs.getString(2) + "/t"); System.out.print(rs.getInt(3) + "/t"); System.out.print(rs.getDate(4) + "/t"); System.out.print(rs.getInt(5) + "/t"); System.out.println (); while(rs.next()) { System.out.print(rs.getString(1) + "/t"); System.out.print(rs.getString(2) + "/t"); System.out.print(rs.getInt(3) + "/t"); System.out.print(rs.getDate(4) + "/t"); System.out.print(rs.getInt(5) + "/t"); System.out.println (); } } }catch(SQLException ce) { System.out.println (ce); } } public static void main(String[] args) { CourseAppl retObj = new CourseAppl(); retObj.getConnection(); retObj.display(); } } 资料引用:http://www.knowsky.com/343956.html
