----------------------------------
Summary: sql-migration-guide wrong description
Key: SPARK-37692
URL: https://issues.apache.org/jira/browse/SPARK-37692
Project: Spark
Issue Type: Documentation
Components: Documentation
Affects Versions: 3.2.0
Reporter: JacobZheng
Description in the documentation:
{code:java}
//代码占位符
In Spark 3.2, the unit list interval literals can not mix year-month fields
(YEAR and MONTH) and day-time fields (WEEK, DAY, …, MICROSECOND). For example,
INTERVAL 1 day 1 hour is invalid in Spark 3.2. In Spark 3.1 and earlier, there
is no such limitation and the literal returns value of CalendarIntervalType. To
restore the behavior before Spark 3.2, you can set
spark.sql.legacy.interval.enabled to true. {code}
”INTERVAL 1 day 1 hour is invalid in Spark 3.2.“
Is this example correct? According to the description of DayTimeIntervalType,
INTERVAL 1 day 1 hour is valid in Spark 3.2
