用于连接到 Sql Server 并从 Eclipse 运行示例查询的 Java 程序

Question

package sqlselection;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class Sqlselection 
    {
        public static void main(String[] args)
        {
            try
            {
                Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");

                String userName = "sa";
                String password = "password";
                String url = "jdbc:microsoft:sqlserver://localhost:1433"+";databaseName=AdventureWorks2008R2";
                Connection con = DriverManager.getConnection(url, userName, password);
                Statement s1 = con.createStatement();
                ResultSet rs = s1.executeQuery("SELECT TOP 1 * FROM HumanResources.Employee");
                String[] result = new String[20];
                if(rs!=null){
                    while (rs.next()){
                        for(int i = 0; i <result.length ;i++)
                        {
                            for(int j = 0; j <result.length;j++)
                            {
                                result[j]=rs.getString(i);
                            System.out.println(result[j]);
                        }
                        }
                    }
                }

                //String result = new result[20];

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

以上是我连接到 Sql 服务器以从 eclipse 运行示例选择查询的示例程序。

我收到以下错误。

java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver
    at java.net.URLClassLoader$1.run(Unknown Source)

    at sqlselection.Sqlselection.main(Sqlselection.java:13)

我已将 sqljdbc.jar、sqljdbc4.jar 添加到库中。帮助解决这个问题

Answer 1

问题出在 Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver"); 这一行。类限定名错误

是sqlserver.jdbc不是jdbc.sqlserver
