             Summary: Refine ANSI error messages and remove 'To return NULL instead'
                 Key: SPARK-39392
                 URL: https://issues.apache.org/jira/browse/SPARK-39392
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.4
            Reporter: Vitalii Li


Proposal: remove ‘To return NULL instead’ as this should not be the purpose and the user may not even aware it was returning NULLs.

Example:

Old:
{{1[MAP_KEY_DOES_NOT_EXIST] Key 3 does not exist. To return NULL instead, use `try_element_at`. If necessary set "spark.sql.ansi.enabled" to "false" to bypass this error.2== SQL(line 1, position 8) ==3SELECT m[3] FROM VALUES(map(1, 'Hello', 2, ...4       ^^^^}}
Proposed:
{{1[MAP_KEY_DOES_NOT_EXIST] Key 3 does not exist in the map. Use `try_element_at` to tolerate a non-existent key and return NULL. If necessary set "spark.sql.ansi.enabled" to "false" to bypass this error.2== SQL(line 1, position 8) ==3SELECT m[3] FROM VALUES(map(1, 'Hello', 2, ...4       ^^^^}}
