JSP和SQL SERVER 2000连接问题

[wyxixi78]

使用以下代码测试连接：
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
String url = "jdbc:microsoft:sqlserver://localhost:1433";
String user = "sa";
String password = "123456";
Connection conn = DriverManager.getConnection(url,user,password);
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql = "select * from employee";
ResultSet rs = stmt.executeQuery(sql);
错误提示：
org.apache.jasper.JasperException: [Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]对象名 'employee' 无效。

请高手们不吝赐教！！！！

[weepp]

上为正解！

[CQ_LW]

我有一个连接类，你试一下
import java.sql.*;
import java.util.*;
import javax.servlet.http.HttpServlet;
/*
*数据连接类
*/

public class DBConn {
private String userid = "sa";
/*连接字符串*/
private String conn_str = "jdbc:microsoft:sqlserver://192.168.2.132:1433;SelectMethod=Cursor;DatabaseName=pubs";
private String pwd = "";
/*sql驱动*/
private String classFor = "com.microsoft.jdbc.sqlserver.SQLServerDriver";
public Connection dConn = null;

java.util.Vector batchSQL = new java.util.Vector();

public DBConn() {
try {
Class.forName(classFor);
dConn = DriverManager.getConnection(conn_str, userid, pwd);
System.out.println("Database connection is connected ! ");
}
catch (Exception ex) {
System.out.println("Database connection is not connected ! ");
System.out.println("DBConn.DBConn" + ex.toString()) ;

}
}

这个很简单，只是你连接数据库的时候没有指明要连哪个数据库呀，修改如下：
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=pm";
//注:pm为employee表坐在的数据库名

[36397]

靠，靠……

你都没有指明数据库，他肯定说你出错的了。

靠，靠……

[skyboy0720]

已经很清楚了啊！对象名 'employee' 无效。
检查看看连接的数据库下有没有这个表！！！

[wyxixi78]

修正：url = "jdbc:microsoft:sqlserver://localhost:1433;databasename = pubs";

[wyxixi78]

有这个表的

[alpha80]

要看这个表是属于那个database 楼上的楼上正解,;databasename = pubs
看看'employee' 属于那个database

[wyxixi78]

我刚才试过查询master数据库中的表就可以，查pubs的就不行，为什么啊？

[wyxixi78]

改成,;databasename = pubs就会提示url无效；employee是属于pubs的。

[zawx]

加模式名ado.employee

[jein]

楼主，你没有指定是使用哪个数据库啊，程序没有办法执行
String sql = "select * from employee";
这条语句

[jein]

晕，不好意思，我看到你的跟帖了,你最好把该页面的所有代码帖出来

[gexu]

你没有指定数据库的名字!

[wyxixi78]

我明明已经指明数据库了，后面不是有纠正吗？你们都没看。。。。。。：（

[香芋元宇宙]

[Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]对象名 'employee' 无效。
这句话表明数据库中可能没有这个表，或者表名写错了
