[jira] [Created] (KYLIN-5272) The "case when" command may cause the field value to be different from the user's expectation.

GuKe created KYLIN-5272:
---------------------------

             Summary: The "case when" command may cause the field value to be different from the user's expectation.
                 Key: KYLIN-5272
                 URL: https://issues.apache.org/jira/browse/KYLIN-5272
             Project: Kylin
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: v2.6.3, v2.2.0
            Reporter: GuKe
         Attachments: issue.jpg

When using "Case then" to set a fixed character value for a field, Kylin uses Spaces to complete the length of string to 32. This will cause the field to display characters that are actually different from the user's expected values, causing query errors, Example a failed Join operation.
