If I have a Array[String]
that contains the columns I need to use in select()
function, how I can apply them in the most designed way?
.select(from_json(col("value").cast("string"), schema).as("data"), col("oneColumn"))
I'd like to put several columns with names from the array in the place of col("oneColumn")
ANswers from here can't help me, as they deal with Lists of Strings, while I already have a Column
object and can't apply collection of columns as a parameter of select()
