在我的以下程序中,我尝试在Windows身份验证中使用jdbc连接MSSQL Server.但得到以下错误

import java.io.*;
import java.sql.*;
import java.util.GregorianCalendar;
import java.util.Date;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;

class  Cms_truncate
{
    public static void main(String[] args) 
    {
         Calendar cal = new GregorianCalendar();

         //String name="cmscim";
         //String filename = "D:\\programs\\Tomcat 6.0\\webapps\\timescape\\canteen_scheduller\\CMS_CSV\\cms_cim\\"+ name+"-"+cal.get(Calendar.YEAR) +"-" +(cal.get(Calendar.MONTH)+1) + "-"+cal.get(Calendar.DATE)+".csv";
         Connection conn = null;
         String url = "jdbc:sqlserver://localhost:1433;databasename=CMS_TIMES_MAIN;integratedSecurity=true";
         String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
         String userName = ""; 
         String password = "";
         Statement stmt;
         try
         {

         Class.forName(driver);//.newInstance();
         conn = DriverManager.getConnection(url,userName,password);
         String query = "select * from cim where sapId=10025331";
         stmt …

我在windows身份验证中在localhost上运行此代码片段但是出现了以下错误,但我已经在我的类路径中添加了sqljdbc4 jar,并且在从eclipse运行时我也在构建路径中添加了jar

import java.io.*;
import java.sql.*;
import java.util.GregorianCalendar;
import java.util.Date;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;

class  Cms_truncate
{
    public static void main(String[] args) 
    {
         Calendar cal = new GregorianCalendar();

         //String name="cmscim";
                 Connection conn = null;

         String url = "jdbc:sqlserver://localhost\SQLEXPRESS;databasename=yatin";
         String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
         String userName = ""; 
         String password = "";
         Statement stmt;
         try
         {

         Class.forName(driver);//.newInstance();
         conn = DriverManager.getConnection(url,userName,password);
         String query = "truncate table cim";
         stmt = conn.createStatement();
         int flag = stmt.executeUpdate(query);
         System.out.println("flag = "+flag); 
         conn.close();
        System.out.println("");
         } catch …

我有一个查询我正在使用以下查询从MySQL中选择记录

mysql> select VID from tm_visitor where DATE(INTIME)=DATE('2012-08-01');

然后我得到了结果

+--------+
| VID    |
+--------+
| 000001 |
| 000002 |
| 000003 |
| 000004 |
+--------+
4 rows in set (0.00 sec)

但是当我使用查询时

mysql> select VID from tm_visitor where DATE(INTIME)=DATE('01-AUG-2012'); 

它什么都没给我

Empty set, 8 warnings (0.00 sec)

怎么解决这个？

java.net.MalformedURLException: no protocol: "localhost/uatpw/ActiveTransaction"?isx=E13F42EC5E38
    at java.net.URL.<init>(URL.java:567)
    at java.net.URL.<init>(URL.java:464)
    at java.net.URL.<init>(URL.java:413)

从包含localhost的url读取数据时格式错误的URL异常.

其实我的程序如下

package bll.sap;

import java.net.MalformedURLException;

import utility.PropertyUtility;

public class GetActiveData 
{
    public static void main(String[] args) {

        String sapURL = "";

        try {


            sapURL = PropertyUtility.getSapURL();


            //Get Summary Data
            SapDataSync sapDataSync = new SapDataSync();

            //sapDataSync.readTransactionJsonFromUrl(sapURL+"?isx=false");
            sapDataSync.readTransactionJsonFromUrl(sapURL+"?isx=E13F42EC5E38");

            } 
        catch(MalformedURLException me)
        {
            me.printStackTrace();
        }   
        catch (Exception e) {
                e.printStackTrace();
        }
    }









}

和
