[jira] [Created] (SPARK-36023) Confusing error from casting a string to ANSI interval

Max Gekk created SPARK-36023:
--------------------------------

             Summary: Confusing error from casting a string to ANSI interval
                 Key: SPARK-36023
                 URL: https://issues.apache.org/jira/browse/SPARK-36023
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: Max Gekk


See the example:

{code:sql}
spark-sql> select interval '56:12' minute to second;
0 00:56:12.000000000
spark-sql> select cast('56:12' as interval minute to second);
21/07/05 22:58:03 ERROR SparkSQLDriver: Failed in [select cast('56:12' as interval minute to second)]
java.lang.IllegalArgumentException: Interval string does not match day-time format of `[+|-]h`, `INTERVAL [+|-]'[+|-]h' HOUR` when cast to interval minute to second: 56:12
	at org.apache.spark.sql.catalyst.util.IntervalUtils$.checkStringIntervalType$2(IntervalUtils.scala:287)
{code}
The error message from the second command confuses slightly. It mentions INTERVAL HOUR but how it relates to the input?
