[jira] [Commented] (CALCITE-5113) function week(date 'xxx') returns a different number than mysql
[ https://issues.apache.org/jira/browse/CALCITE-5113?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17528482#comment-17528482 ]
itxiangkui commented on CALCITE-5113:
-------------------------------------
We carefully understood the iso-8601 standard, and the behavior of calcite is correct.
in addition:
{code:java}
1 row selected (0.759 seconds)
0: jdbc:avatica:remote:url=http://10.192.11.4> select week(date '2022-01-01',10);
+-------+
| EXPR$0 |
+-------+
| 52 |
+-------+ {code}
This behavior seems a little strange, the second parameter "mode" seems to be ignored forever
But I temporarily closed this issue
