["Khurram Faraaz (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-5361?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15929428#comment-15929428 ] 

Khurram Faraaz commented on DRILL-5361:
---------------------------------------

The below usage of CURRENT_DATE without open and close parentheses gives results. Not sure if this is a documentation issue or if this is a design issue.
This is from Drill 1.10.0

{noformat}
0: jdbc:drill:schema=dfs.tmp> select CURRENT_DATE FROM (values(1));
+---------------+
| CURRENT_DATE  |

| 2017-03-17    |

>             Project: Apache Drill
>          Issue Type: Bug
>    Affects Versions: 1.10.0
>            Reporter: Paul Rogers
>
> The [Drill documentation|http://drill.apache.org/docs/date-time-functions-and-arithmetic/] describes a CURRENT_DATE() function. Tried the following query:
> {code}
> SELECT CURRENT_DATE() FROM (VALUES(1))
> {code}
> Got the following errors:
> {code}
> SEVERE: org.apache.calcite.sql.validate.SqlValidatorException: No match found for function signature CURRENT_DATE()
> SEVERE: org.apache.calcite.runtime.CalciteContextException: From line 1, column 8 to line 1, column 21: No match found for function signature CURRENT_DATE()
> {code}
> Please:
> * Implement the function, or
> * Remove the function from the documentation, or
> * Leave the function in the docs, but add a footnote saying that the function is not yet available.
