["Xiangdong Huang (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IOTDB-831?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17175919#comment-17175919 ] 

Xiangdong Huang commented on IOTDB-831:
---------------------------------------

This is a general grammar in MySQL (as well as SQL server), 

so, supporting it is ok.

 

What's more, I think what we need to do is implementing a real PreparedStatement, which saves SQL parsing time cost a lot.
