Subject [jira] [Commented] (DRILL-1757) Add support for wildcards within REPEATED_CONTAINS
Date Wed, 07 Jan 2015 19:46:34 GMT

    [ https://issues.apache.org/jira/browse/DRILL-1757?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14268102#comment-14268102

Venkata krishnan Sowrirajan commented on DRILL-1757:
----------------------------------------------------

Microsoft's SQL server supports contains(), similar convention is followed for repeated_contains().
Below is the documentation for contains() in MS SQL

Review request created. I have also added the patch here as an attachment.

> REPEATED_CONTAINS does not seem to support the % or * wildcard. If this is expected behavior
(I assume not), it needs to be documented.
