------------------------------------
Summary: Adds `random()` sql function
Key: SPARK-28086
URL: https://issues.apache.org/jira/browse/SPARK-28086
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 3.0.0
Reporter: Dylan Guedes
Currently, Spark does not have a `random()` function. Postgres, however, does.
For instance, this one is not valid:
{code:sql}
SELECT rank() OVER (ORDER BY rank() OVER (ORDER BY random()))
{code}
Because of the `random()` call. On the other hand, [Postgres has
it.|https://www.postgresql.org/docs/8.2/functions-math.html]
