--------------------------------
Summary: Support SQL split_part function
Key: SPARK-38063
URL: https://issues.apache.org/jira/browse/SPARK-38063
Project: Spark
Issue Type: Task
Components: SQL
Affects Versions: 3.3.0
Reporter: Rui Wang
`split_part()` is a commonly supported function by other systems such as
Postgres, Snowflake, Redshift.
The Spark equivalent (please double check) is `element_at(split(arg, delim),
part)`
Note that Snowflake supports negative index which counts from the back. We
should automatically support that by using `element_at()`.
If any input parameter is NULL, return NULL.
