Sean Hsuan-Yi Chu created DRILL-3971:
----------------------------------------
Summary: to_date(timestamp) is supported
Key: DRILL-3971
URL: https://issues.apache.org/jira/browse/DRILL-3971
Project: Apache Drill
Issue Type: Task
Components: Documentation
Reporter: Sean Hsuan-Yi Chu
Assignee: Kristine Hahn
Do a search for "to_date" in this link:
https://drill.apache.org/docs/data-type-conversion/
We would find that it says these two are supported:
1. expression is a character string enclosed... (rest is omitted)
2. 'format' is a format specifier enclosed... (rest is omitted)
Due to DRILL-3769, let's add one more supported case: expression can be
timp_stamp type.
A example would be:
{code }
0: jdbc:drill:zk=local> select to_date(to_timestamp(1000000000)) from
(VALUES(1));
+-------------+
| EXPR$0 |
+-------------+
| 2001-09-09 |
+-------------+
{code }
Note that to_timestamp(1000000000) would generate a timestamp with value
2001-09-08 18:46:40.0 (on MAC, which can be different on Linux )
