Hi David
If you need alternative way to do it you can use below:
df.select(expr("stack(2, 1,2,3)"))
Or
df.withColumn('stacked', expr("stack(2, 1,2,3)"))Thanks Khalid On Mon, 14 Jun 2021, 10:14 , <[email protected]> wrote: > I noticed that the stack SQL function > <https://spark.apache.org/docs/latest/api/sql/#stack> is missing from the > functions > API > <https://spark.apache.org/docs/3.1.2/api/java/org/apache/spark/sql/functions.html>. > Could we add it? >
