[jira] [Resolved] (SPARK-27429) [SQL] to_timestamp function with
additional argument flag that will allow exception if value could not be
cast
[ https://issues.apache.org/jira/browse/SPARK-27429?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hyukjin Kwon resolved SPARK-27429.
----------------------------------
Resolution: Won't Fix
Then you should introduce {{try}} function, not the flag. That's a different idea. Don't reopen this.

> Priority: Major

> If I am running a SQL on a csv based dataframe and my query has to_timestamp(input_col,'yyyy-MM-dd HH:mm:ss'), if the values in input_col are not really timestamp like 'ABC' then I would like to_timestamp function to throw an exception rather than happily (silently) return the values as null.
