     [ https://issues.apache.org/jira/browse/SPARK-38063?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Rui Wang updated SPARK-38063:
-----------------------------
    Description: 
`split_part()` is a commonly supported function by other systems such as Postgres and some other systems.

The Spark equivalent (please double check) is `element_at(split(arg, delim), part)`

If any input parameter is NULL, return NULL.

  was:
`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.
