package ssd;

import java.sql.Connection;

import java.sql.ResultSet;
import java.sql.Statement;

public class sdd {
	public static void main(String[] srg) {
		String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"; // 加载JDBC驱动
		String dbURL = "jdbc:microsoft:sqlserver://127.0.0.1:1433; DatabaseName=lianxi"; // 连接服务器和数据库

出现 java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]对象名 'users' 无效。 ?at com.microsoft.jdbc.base.BaseExceptions.createException(Unknown Source) ?at com.microsoft.jdbc.base.BaseExceptions.getException(Unknown Source) ?at com.microsoft.jdbc.sqlserver.tds.TDSRequest.processErrorToken(Unknown Source) ?at com.microsoft.jdbc.sqlserver.tds.TDSRequest.processReplyToken(Unknown Source) ?at com.microsoft.jdbc.sqlserver.tds.TDSExecuteRequest.processReplyToken(Unknown Source) ?at com.microsoft.jdbc.sqlserver.tds.TDSRequest.processReply(Unknown Source) ?at com.microsoft.jdbc.sqlserver.SQLServerImplStatement.getNextResultType(Unknown Source) ?at com.microsoft.jdbc.base.BaseStatement.commonTransitionToState(Unknown Source) ?at com.microsoft.jdbc.base.BaseStatement.postImplExecute(Unknown Source) ?at com.microsoft.jdbc.base.BaseStatement.commonExecute(Unknown Source) ?at com.microsoft.jdbc.base.BaseStatement.executeQueryInternal(Unknown Source) ?at com.microsoft.jdbc.base.BaseStatement.executeQuery(Unknown Source) ...... 代码中: String dbURL = "jdbc:microsoft:sqlserver://localhost:1433; DatabaseName=XXX 注意到了localhost:1433;后面有一空格，这样就找不到Database了，肯定也就找不到其中的数据表了。
