[jira] [Comment Edited] (DRILL-3610) TimestampAdd/Diff (SQL_TSI_)
functions
[ https://issues.apache.org/jira/browse/DRILL-3610?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16729429#comment-16729429 ]

Hi, [~bbevens], thanks for adding the docs!
There is a mistake in the queries for {{TIMESTAMPADD}}: this UDF should accept not varchar values as the last argument, but date, time or timestamp values.
So the next query works correctly:
{code:sql}
SELECT TIMESTAMPADD(MINUTE,1,date '2003-01-02');
{code}
{noformat}
+------------------------+
| EXPR$0 |
+------------------------+
| 2003-01-02 00:01:00.0 |
+------------------------+
1 row selected (1.066 seconds)
{noformat}
Could you please modify docs to reflect that for both {{TIMESTAMPADD}} and {{TIMESTAMPDIFF}} UDFs?
