[jira] [Commented] (SPARK-33883) Can repeat "where" twice without error in spark sql

    [ https://issues.apache.org/jira/browse/SPARK-33883?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17255515#comment-17255515 ] 

Liu Neng commented on SPARK-33883:
----------------------------------

the first where is a table alias,

you can try 'select where.* from person where where name is not null'.

you can set spark.sql.ansi.enabled=true to raise an exception in this case.

so I think it is not an issue.
