我使用以下代码：

Dataset <Row> dataframee =  df1.as("a").join(df2.as("b"),
            df2.col("id_device").equalTo(df1.col("ID_device_previous")).
                    and(df2.col("id_vehicule").equalTo(df1.col("ID_vehicule_previous"))).
                and(df2.col("tracking_time").lt(df1.col("date_track_previous")))
            ,"left").selectExpr("a.*", "b.ID_tracking as ID_pprevious", "b.km as KM_pprevious","b.tracking_time as tracking_time_pprevious","b.speed as speed_pprevious");

我从df2Dataframe获得了df1Dataframe与多行的连接。
但我想加入 df1 Dataframe df2 相同条件和顺序下的Dataframe df2.col("tracking_time") desc limit(0,1) 编辑
我尝试了下面的代码，但不起作用。

df1.registerTempTable("data");
df2.createOrReplaceTempView("tdays");
Dataset<Row> d_f = sparkSession.sql("select a.*  from data as a  LEFT JOIN (select  b.tracking_time from tdays as b where  b.id_device = a.ID_device_previous and  b.id_vehicule = a.ID_vehicule_previous  and b.tracking_time < a.date_track_previous order by b.tracking_time desc limit 1 )");

我需要你的帮助
