我们可以使用Java对天蓝色的宇宙图进行SQL调用吗？

Question

我希望在我的宇宙图应用程序中实现部分匹配。 由于cosmos图不支持gremlin中的lambda表达式，因此我想在cosmos db（相同的图连接）中触发sql包含查询。 但是我在连接db时面临困难。认为我指定了错误的数据库，用户名或主机（与将其用于图形连接时相同）。请在下面找到我的代码并提供建议。

 public static void main(String[] args) {

     // Connect to database
        String hostName = "";//your_server.database.windows.net
        String dbName = "";
        String user = "";
        String password = "";
        String url = String.format("jdbc:sqlserver://%s:1433;database=%s;user=%s;password=%s;encrypt=true;hostNameInCertificate=*.database.windows.net;loginTimeout=30;", hostName, dbName, user, password);
        Connection connection = null;

        try {
                System.out.println("Started program.......");
                connection = DriverManager.getConnection(url);
                String schema = connection.getSchema();

                        while (resultSet.next())
                        {
                            System.out.println(resultSet.getString(1) + " "
                                + resultSet.getString(2));
