您可以选择
data.bar.baz为

df.show()+-------+| data|+-------+|[3,[2]]|+-------+df.printSchema()root |-- data: struct (nullable = false) | |-- foo: long (nullable = true) | |-- bar: struct (nullable = false) | | |-- baz: long (nullable = true)
在pyspark中：
import pyspark.sql.functions as Fdf.select(F.col("data.foo").alias("foo"), F.col("data.bar.baz").alias("bar.baz")).show()+---+-------+|foo|bar.baz|+---+-------+| 3| 2|+---+-------+
