我有以下数据帧:
+-------------+-----------------+------------------+
|longitude |latitude |geom |
+-------------+-----------------+------------------+
|-7.07378166 |33.826661 [00 00 00 00 01 0..|
|-7.5952683 |33.544191 [00 00 00 00 01 0..|
+-------------+-----------------+------------------+
我使用以下代码:
Dataset<Row> result_f = sparkSession.sql("select * from data_f where ST_WITHIN(ST_GeomFromText(CONCAT('POINT(',longitude_f,' ',latitude_f,')',4326)),geom)");
result_f.show();
但我得到以下错误:
java.lang.ClassCastException: [B cannot be cast to org.apache.spark.sql.catalyst.util.ArrayData
at org.apache.spark.sql.geosparksql.expressions.ST_Within.eval(Predicates.scala:105)
编辑
longitude : Double type
latitude : Double type
geom : Binary type
知道吗?我需要你的帮助
谢谢
我认为ST_GeomFromText不适用于从文本构建几何体,但有:
- ST_GeomFromWKT
- ST_GeomFromWKB
- ST_GeomFromGeoJSON
- ST_点
- ST_PointFromText
- ST_PolygonFromText
- ST_LineStringFromText
- ST_PolygonFrom信封
- ST_圆形
我建议使用ST_Point
或ST_PointFromText
,然后使用谓词ST_WITHIN
类似这样的东西:
Dataset<Row> result_f = sparkSession.sql("select * from data_f where ST_WITHIN(ST_Point(CAST(data_f.latitude AS Decimal(24,20)), CAST(data_f.longitude AS Decimal(24,20))),geom)");
result_f.show();
