[jira] [Commented] (IOTDB-466) Modify sql grammar

    [ https://issues.apache.org/jira/browse/IOTDB-466?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17032874#comment-17032874 ] 

Xiangdong Huang commented on IOTDB-466:
---------------------------------------

+1 for the changes.

For the first one, do not forget to modify relate function names in the sourceCode rather than just SQL grammar.

e.g., isGroupByDevice.
