1.安裝:SQL Server 2000 Driver for JDBC Service Pack 3
下載安裝JDBC SP3
//www.VeVB.COm/softs/234108.html
裡面的安裝包
按照提示安裝可以了.成功後有三個檔案要使用:
c:/program files/Microsoft SQL Server 2000 Driver for JDBC/lib/msbase.jar
c:/program files/Microsoft SQL Server 2000 Driver for JDBC/lib/msutil.jar
c:/program files/Microsoft SQL Server 2000 Driver for JDBC/lib/mssqlserver.jar
2.測試程式碼
新類別檔案Connect.java.
package test;import java.*;import java.sql.Driver;public class Connect{ private java.sql.Connection con = null; private final String url = "jdbc:microsoft:sqlserver://"; private final String serverName= "localhost"; private final String portNumber = "1433"; private final String databaseName= "DBtest"; private final String userName = "sa"; private final String password = "123456"; // Informs the driver to use server a side-cursor, // which permits more than one active statement // on a active statement // on a connection. private final String selectMethod = "cursor"; // Constructor public Connect(){} private String getConnectionUrl(){ return url+serverName+":"+portNumber+";databaseName="+databaseName+";selectMethod="+selectMethod+";"; } private java.sql.Connection getConnection(){ trytry { Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver"); con = java.sql.DriverManager.getConnection(getConnectionUrl(),userName,password); if(con!=null) System.out.println("Connection Successful!"); }catch(Exception e){ e.printStackTrace(); System.out.println("Error Trace in getConnection() : " + e.getMessage()); } return con; } /* Display the driver properties, database details */ public void displayDbProperties(){ java.sql.DatabaseMetaData dm = null; java.sql.ResultSet rs = null; try{ con= this.getbase(); if(con!=null){ dm = con.getMetaData(); System.out.println("Driver Information"); System.out.println("/tDriver Name: "+ dm.getDriverName()); System.out.println("/tDriver Version: "+ dm.getDriverVersion ()); System.out.println("/nDatabase Information "); System.out.println("/tDatabase Name: "+ dm.getDatabaseProductName()); System.out.println("/tDatabase Version: "+ dm.getDatabaseProductVersion()); System.out.println("Avalilable Catalogs "); rs = dm.getCatalogs(); while(rs.next()){ System.out.println("/tcatalog: "+ rs.getString(1)); } rs.close(); rs = null; closeConnection(); }else System.out.println("Error: No active Connection"); }catch(Exception e){ e.printStackTrace(); } dm=null; } private void closeConnection(){ try{ if(con!=null) con .close(); con=null; }catch(Exception e){ e.printStackTrace(); } } public static void main(String[] args) throws Exception { Connect myDbTest = new Connect(); myDbTest.displayDbProperties(); }}代碼來源:

成功後控制台輸出:

3.問題:
在測試中控制台老輸出下面的錯誤!
找資料找了很久.都說把jdbc安裝後的三個jar檔案的路徑放進環境變數裡可以了但我試了不行的!
java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver
....
Error Trace in getConnection() : com.microsoft.jdbc.sqlserver.SQLServerDriver
Error: No active Connection
請教了別人才找到方法:
套件資源管理器-->套件名稱右鍵"建置路徑"-->配置建置路徑-->java建置路徑-->庫-->新增外部JAR
把那三個JAR選擇進去就可以了.
新增後三個JDBC檔案就有了.
