[jira] [Commented] (TAJO-352) Implement right/left(text, size) function

    [ https://issues.apache.org/jira/browse/TAJO-352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13836232#comment-13836232 ] 

Hyunsik Choi commented on TAJO-352:
-----------------------------------

If the second parameter (i.e., size) is null, the result should be null. Others look great for me.
