Would anyone know if there in an equivalent function similar to the pyspark function pyspark.sql.functions.posexplode()
in presto?
I am trying to explode and array with its index. I am aware of the existence of UNNEST()
. However, this does not store the index of the value in the array.

Update - I have found the answer
CROSS JOIN UNNEST('col_wth_array')
WITH ORDINALITY AS t ('value', 'position');
