[jira] [Commented] (PIG-2303) Documentation says the MAX function can be used on chararray, but it can't

["Graham Lea (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-2303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13114431#comment-13114431 ] 

Graham Lea commented on PIG-2303:
---------------------------------

Note: The error I was getting on entering the line using MIN + MAX into Grunt was:
{code}
ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1022: Type mismatch merging schema prefix. Field Schema: double. Other Field Schema: fieldName: chararray
{code}
(Just adding this to help people searching for this error message to find a solution.)

> It says MIN/Max can be used on chararray, but the result of those functions is always a double.
> Had to search through the Pig Javadoc to find that I should use StringMin/StringMax instead.
