Subject [jira] [Commented] (TAJO-378) Implement concat_ws function.
Date Wed, 04 Dec 2013 08:34:35 GMT

    [ https://issues.apache.org/jira/browse/TAJO-378?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13838728#comment-13838728

Seungun Choe commented on TAJO-378:
-----------------------------------

This function's definition is, concat_ws(sep text, str "any" [, str "any" [, ...] ]).
For example, concat_ws(',', 'abcde', 2, NULL, 22)'s result is abcde,2,22.
Detailed description is "Concatenate all but first arguments with separators. The first parameter
is used as a separator. NULL arguments are ignored.".  :)

> Implement concat_ws function.
