Key: SPARK-43492
URL: https://issues.apache.org/jira/browse/SPARK-43492
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.4.0
Reporter: Max Gekk
Assignee: Max Gekk
Spark supports the DATE_ADD and DATE_DIFF functions with 2 arguments but when
an user calls the same functions with 3 arguments, Spark SQL outputs the
confusing error:
{code:sql}
spark-sql (default)> select date_add(MONTH, 1, date'2023-05-13');
[UNRESOLVED_COLUMN.WITHOUT_SUGGESTION] A column or function parameter with name
`MONTH` cannot be resolved. ; line 1 pos 16;
'Project [unresolvedalias('date_add('MONTH, 1, 2023-05-13), None)]
