说明 在调试模式和使用 Eclipse 时,此 Android 代码处理行: con = DriverManager.getConnection(connectionUrl); 它会在 Logcat 中产生错误,例如:
错误

代码 这只是这个类的一部分:
import java.sql.*;
public class ConnectURL {
public static void main() {
// Create a variable for the connection string.
String connectionUrl = "jdbc:sqlserver://192.168.1.20:1433;" +
"databaseName=BD;user=sa;password=pass1;integratedSecurity=true;";
// Declare the JDBC objects.
Connection con = null;
Statement stmt = null;
ResultSet rs = null;
try {
// Establish the connection.
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
con = DriverManager.getConnection(connectionUrl);
....
注意我已经在一个文件夹中下载了 Microsoft sqlserver jdbc 4.0,并且在这个项目中有一个带有这个路由的 Java 构建路径。
