android 如何连接sqlserver数据库

临文乍了了，彻卷兀若无。这篇文章主要讲述android 如何连接sqlserver数据库相关的知识，希望能为你提供帮助。
步骤如下：
1.下载jar包：jtds-1.3.1.jar；
2.将jtds-1.3.1.jar直接拷贝到项目下的app下的libs文件夹下；
3.创建java类：

package com.example.zhouy.mytest01; import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.SQLException; import java.sql.Statement; /** * Created by Administrator on 2017/12/14. */public class DBUtil { private static Connection getSQLConnection(String ip,String user,String pwd,String db) { Connection con =null; try { Class.forName("net.sourceforge.jtds.jdbc.Driver"); con = DriverManager.getConnection("jdbc:jtds:sqlserver://"+ip+":1433/"+db+"; charset=utf-8",user,pwd); } catch (ClassNotFoundException e) { e.printStackTrace(); } catch (SQLException e) { e.printStackTrace(); } return con; }public static String QuerySQL(){String result=""; try { Connection conn = getSQLConnection("192.168.1.xx","xx","xxx","DATABASE"); String sql = "select top 10 * from users"; Statement stmt = conn.createStatement(); ResultSet rs = stmt.executeQuery(sql); while(rs.next()) { String s1 = rs.getString("USRNAM"); String s2 = rs.getString("FULLNAME"); result += s1+" - " + s2 + "\n"; System.out.println(s1+" - "+s2); } rs.close(); stmt.close(); conn.close(); } catch (SQLException e) { e.printStackTrace(); result += "查询数据异常！"+e.getMessage(); } return result; }public static void main(String[] args){ QuerySQL(); } }

直接运行即可测试是否连接成功；
如果出现failed to create directory错误请看上一篇博文；
如果出现android 中Network error IOException: failed to connect to /127.0.0.1 (port 1433): connect failed: ECONNREFUSED (Connection refused)错误请看上一篇博文；
