我正在尝试通过 pyspark 构建 sql 来实现这一点。目标是将多行组合成单行示例：我想将其转换为
+-----+----+----+-----+
| col1|col2|col3| col4|
+-----+----+----+-----+
|x | y | z |13::1|
|x | y | z |10::2|
+-----+----+----+-----+
到
+-----+----+----+-----------+
| col1|col2|col3| col4|
+-----+----+----+-----------+
|x | y | z |13::1;10::2|
+-----+----+----+-----------+
